Kuron: yeah that's the point, this framework is pretty much useful to everyone making games in Max as is a decent sprite routine. Some of Indiepath's graphics ones are more useful for specific types of games/applications like Aurora is. Other modules of Indiepath's, like sound and delta timing, are useful to everyone though, I'd have thought. However, fixed rate logic is more reliable for collision detection that delta timing unless you program special workarounds using delta timing - not easy.
