Any data associated with the scripts will be in the comments of the script itself... I could add special things but for simplicity reasons, MP2 will consider any script installed in its directory as being usable, that's all. The only information it will display about them in their name. It may change as I'Ve seen that apparently XML tags can be added to VBScript/JScript... we'll see.
About security and the patch related to it, don't worry, as strange as it can seems, MP2 is not a network related software so I don't need to be careful about what resource users will access. I just have to double check my string size and nobody will be able to do anything I don't allow. For things like storing high scores, a PropertyBag object will be available and will store whatever value the user want in a regkey decided my MP2 itself... no, really, I think you shouldn't care too much about security... you'll be able to test it in the Alpha version and that will be sufficient... talking about it too much will afraid people won't don't know nothing about it.
For all of them, I repeat: scripting will be disabled by default in MP2 so if you don't want it, just forget about it
Patchou.
