Yeah, it's great for some kinds of projects. For example it's used for
ghc. However it is very centralised, synchronous and needs ssh on

What we've implemented is using cabal-install to generate build logs and
summary info and to upload that to the hackage server. The advantage is
that we should get an order or two magnitude more results than if we
used a handful of buildbots. It also means we do not have to administer
the buildbots, people can administer their own cabal-install setups. We
don't need to care so much about individual results if we have enough

We plan to have two reporting modes, anonymous with minimal info, and
non-anonymous with full build logs. So far we've got both but have not
separated them yet.
