Haha, I must be more careful of what I say :> I did post a follow up about the initial release but it could have been phrased more clearly.
Yeah I realize the demo is mostly an adaptation but it still just looks so good, and I'm sure you have a good feel about how things all fit together in famous now. Yeah, I really think famous is the way to go (I know people might say I'm not objective because of famous-views, but it's all non-profit and an investment based purely on my belief of the framework).
Obviously it's still only 0.5 (twice now people have gotten really excited about Famous only to be disappointed / underwhelmed expecting production quality so soon). You and I both went through all the iterations of Meteor and shared in the pain. But I guess 0.3 was like Spark and 0.5 like Blaze (if you'll forgive the anaology) -- it's just a front-end framework after all. I imagine more refinements than total API changes moving forward, but could be proved wrong.
I've actually never used open/webgl, so you have an advantage there. Getting into it through famous now, which offers a very nice level of abstraction. But I think where it really shines is the mixed mode. DOM is still the best place for text, SEO, etc... and famous joins these two things seamlessly on the same coordinate system. Also, Steve Newcomb actually stated quite clearly that even though you "could write games in famous", that's really not it's goal... it's designed for creating UI.
Anyway, I digress some 
Love the Day of Glass videos, wish we had more stuff like that more often. Famous-views btw is the only "integration". Famono is just a loader for module management, to import famous with fine grained dependencies - we'll support it as a way of bringing famous into Meteor just like with v0 (the gadicohen:famous is only temporary). But yes raw famous in Meteor is an option too, and there are projects for that too (e.g. moflow).
Glad you liked the example. FYI, famous are also coming out with a templating model with their BEST framework. Details are still quite sketchy but iirc it will be announced at jQuery conf (jun 21/22) and then I think 3-6 month private beta. There's been some ambiguity about whether it tries to replace Meteor, will integrate seamlessly into Meteor without needing something like famous-views, etc. From my side, only very little of famous-views touches famous, most of it is on the Meteor side, so I think probably we'll just integrate with BEST too.
Oh last thing for this really long post... fview-labs is completely unoptimized, but it still sounds like your requests to *.meteor.com (for DDP) are particularly slow. Can you double check that the websocket connection is being established? I think you know, if Meteor can't establish one after a certain amount of time, it just falls back to sockjs... this could account for the delay you're experiencing (as one possibility).
