We just got Meteor compiling on Pogoapp (using a buildpack which uses meteor's git/master, so incorporates these updates[1]), and I booted up open source demo apps whipped up by a couple London developers after a chat in #meteor IRC:

https://github.com/alanshaw/meteor-blackboard

https://github.com/olizilla/goto-meteor

here's live demos (you can use zoom in both):

http://blackboard.pogoapp.com

http://meteor-goto.pogoapp.com/

Be sure to check go take a look at the code, or lack thereof - really impressive stuff. Since looking just a few months ago, the whole meteor ecosystem seems to have expanded and matured at a pretty incredible clip.
