[Buildbot-devel] Is there a build-god? Or any aggregated view for multiple build masters?

I believe that's the new plan. I'm a bit sad to see my jinja setup go 
away, but OTOH a client-side html app is pretty neat too. :)

OT: I'd heartily recommend jQuery as a javascript lib.

I think one can work around that by using JSONP, i.e. fetch a script tag 
that provides continous updates but never closing the connection.
(http://en.wikipedia.org/wiki/JSON#JSONP).

Or the more recent cross-site object sharing for newer browsers:

(http://www.w3.org/TR/access-control/)

Or, failing that, set up the master webserver with proxies to the other 
buildmasters.
