Hi rico
1.:
The money module is created to work with jOpenSim which is a Joomla component, so more or less it is tight to Joomla. Of course, since jOpenSim itself is open source, everyone can investigate ./site/currency.php and ./site/includes/functions_currency.php to see what xmlrpc calls need to be caught and adapt them accordingly.
2.:
First of all: the newest version is not always the best one ... specially not when it comes to dev versions ... we all probably know the experience from some OS that was only usable after SP2 or SP3 came out
I did develop my modules for dev versions of OpenSim in the past, but changes short before the release made lot of my work useless. Some issues with 0.7.6 made me decide to skip this version and 0.8-rc1 is out since 3 days ... I now work on this one and hope to get it done as soon as possible.
3.:
This is my licensing model and I was thinking about this very long time. Wow, 300 regions sometimes ... stresstesting? Do you then have users in there also for stresstesting? Cause the region itself wont do any harm to performance at all
However: if you just need it for stresstesting, you can run the money module in demo mode as well, since stable balance is not required in that case and in that case is no region limit ... if you need it for production, dont hesitate to contact me ... I'm sure we'll find a solution
