Personally, I hope that Twilio goes all-in on the "communications" part of "cloud communications". I'd gladly pay for working and supported IM endpoints with a sane API.
Also, what IM issues did you have? IMified's tech is what's driving the Tropo IM integration, and I'm one of the IMified founders, so I can probably help you with you with that.
MSN works on IMified but doesn't work on Tropo - that's just odd, as you yourself said that the IMified system powers Tropo's IM integration (and the UI at Tropo hints at that from a third party perspective).
The bot.im users still aren't appearing on Google Talk, and I can't seem to add an additional account through GTalk directly.
BTW, though I didn't mention this in our Twitter chat earlier, I far prefer the API that IMified offers to that of Tropo.
