I think this is totally awesome, although only only useful for a few situations.<p>I've only really seen services like this (specifically, most popularly, <a href="http://codepad.org" rel="nofollow">http://codepad.org</a>) used to demonstrate test cases when people are asking for help with their code. The "IDEdroid" app listed on ideone's API page (<a href="http://ideone.com/api" rel="nofollow">http://ideone.com/api</a>) looks interesting though, but yet again, it is an only marginally useful application.
