(no subject)

So I'm looking to flex my malnurished PHP muscles with a new Facebook application. I can't make a "game" (something like Farmville) as my host gets very uppity about that kind of thing. I'm also not interested in making any of those god-forsaken "What X are you?" excuses. I want something really meaty to sink my teeth into. The problem is, I can't think of anything! BandTrack was a nifty idea (it provided gig info and told you what friends might want to join you, it was just very demanding for me as I had to enter in all the gig information manually!) so if anyone can think of something in a similar vein that's what I'm after.

So, anyone got any ideas?
