Mike Lublin will be presenting this feature, and many other cool Meteor related things we do at Qualia (http://qualia.com), at the next Meteor Night on February 23rd. Also, here is a shameless plug for our jobs page; we are hiring lots of engineers
I’m not quite ready to release this as a package, but I’d figure it’d be good to put a demo video out there. No promises, but we will try to release a package at the same time as Mike’s Meteor Talk.
