Figured I would post a quick notice in here also, considering all of the asking and talking I've done here over the past two years or so . I just released my own networking solution, called Bolt, for Unity3D. You can find it over at http://www.boltengine.com

Wow this looks really nice, is there a connection limit? Also do you have to have Unity Pro to use this library?

You do not need Unity Pro, no. It will function even on iOS and Android without Pro (check out the tutorial to see how it works). Bolt is developed for games of 2-128 players, it's not an "MMO SERVER" or anything like that.
