Totally forgot about that.  Well remembered!
 

Never heard of it. No doubt more EU-Bulldust dreamed up by men in suits who have nothing better to do.
 
Not in the EU...the answer for many small businesses; don't sell to EU citizens. That takes away a whole layer of Bulldust.

Nothing to do with osCommerce.

I wonder why you would not have posted this in the dedicated 1.0.7.2 thread?

Phoenix is the official Community Edition of osCommerce, which (in short) means that it is made by the Community and looked after by the Community - that is Shopowners, PRO developers, amateur developers and even some who do not use this software (as they know that the work we do benefits their cart) - all doing their best to make the Project thrive.
Solomono has no input on and no connection to Phoenix. 
I suggest you try both.  That will answer a lot of your questions.

Try it.  If you like it use it.  They are a partner of osCommerce.
Know that if you need support for a 3rd party offering, you are tied to them as that is not allowed on this Forum, so you have to get support by whatever mechanism they themselves provide.

Hard coded.
Hook advice:  make a product_info hook utilising the injectBodyEnd listener.  

As far as I recall, it depends on one thing; whichever "signal" gets back to the shop first.
If the customer arrives back before the IPN...
-or-
If the IPN arrives before the customer.

Which version of Phoenix are you using? IIRC, this was an error introduced in 1.0.7.0, and was quickly fixed in 1.0.7.1.

You will need to contact a good developer and get it re-coded to suit your needs. 
If what is made is better than core, maybe you would then allow us to replace what is in core with your new version.

Use whois to determine where the IP is coming from - if that place is not important, just ban the whole IP range using htaccess.

There is no ability to perform a redirect in admin.  Good news for you is that we are in the process of adding in pre-placed hooks now.
What you need to do is add in a callout, in admin/includes/template_top.php and test it. 
Then let me know where you added and what you added and how you tested it...and it might become core code.
If any of the items in bold are not provided, it definitely will not become core code.

Frozen is EOL (End Of Life) on Monday.  You should therefore avoid it for a new store and as @ecartz rightly says, Phoenix v1.0.6.0 is the de-facto standard of osCommerce;  https://www.oscommerce.com/Products&Download=oscom2ce-phoenix-v1.0.6.0

1.  this thread is not for phoenix
2.  there is a phoenix club
3.  to get a list instead of a grid, set the width of each thing in the display to 12.  It is now a list.

That would not be possible with a core code change in old versions.  The old style page requires each module to be 50%, and this is done using a table, where the modules have no influence over the layout.  In effect, this type of coding is as old as the Ark as the "controller" is the page, not the modules.
Modules are saying:
Here's my Content
Page is saying:
Here's the slot where you are going.
In the recent update, I recoded the page and all the modules to give the modules control over the layout.
Modules are now saying:
Here's my content and here's my width.  Jump.
Page is now saying:
Yes Sir.  How high?

Gary, I assume you mean withOUT a core code change?

Within the next few weeks, I'll be releasing a Supp Code which does something that would be almost ideal to be refactored into a Filtering system...

Base Demo Supporters Demo https://template.me.uk/phoenix/index.php https://template.me.uk/supporters/index.php Support the Project
If you or your employer is commercially dependent on Phoenix (or a previous incarnation), please help to sponsor continual forward movement in the code-base. Phoenix needs you as much as you need Phoenix! I am hopeful that all shopowners, developers, consultants and businesses will support the Project ... allowing two professional developers to work on the code on an ad-hoc basis. A Supporters subscription includes access to the current season of Supporters code as seen at the Supporters Demo shop.

If you up it to Github (as a language branch, not a full download of Phoenix + Russian) I'll link to it from the Phoenix Readme.

This is a setting in Admin > Configuration > My Store.

I believe it would be beneficial to save the RMA request in the Database so that both you and customer can track the status etc.   
Much like how an order is kept track of.
What you have made is the "acorn" of a good idea that someone should run with.
