Hi Carlos,

if you build any extension on TYPO3 you garentee that your code is GPL. 
If you implement that code into your extension you make it GPL and you 
get into conflicts with the InfoSoft, cause you change their license.

This is what I guess you can do:

First you can do, is to ask them for a kind of dual license. MySql does 
something like this.

Second you can do, is to only provide a connector extension, if the 
product has an API to exchange data. This means you only exchange data, 
but you don't include their libraries or their code.

That product itself you use under it's regular license and you install 
it independantly.

I am no lawyer!!!
