I'm loving Goliath -- we plan to put this into production in multiple roles within infochimps.
A few procedurals:
* Just did a pull request for code to do Chunked Transfer Encoded HTTP streaming.
* I have a couple things that might be interesting but are certainly not essential. At your preference and discretion, I'd be glad to publish them into a) postrank-labs/goliath mainline, b) a postrank-labs/goliath_contrib that you set up for "neat but not canonical contribs", or c) infochimps/goliath_chimps for whomever wants it.
Those include:
On 2 & 3: for a lot of things it's useful to have a little embedded control panel. One wouldn't want to have a half-assed Sinatra sprout up in the Goliath repo, but it is nice to be able to say 'haml :dashboard, {stuff}' and have it render {stuff}.
Anyway, let me know which if any are interesting and where you'd like to put them -- I'll send the appropriate pull requests.
