Network library patches

I like Windows. I like networks. I love GHC 6.12.1. Having all three
in combination would be fantastic :-)

Given the Haskell platform will certainly include network (as an
ex-GHC package), does anyone from the haskell-platform team want to
pick up the Windows pieces and put together a working network?

I've got a locally patched version of network, which I'm using with
great success - but that's not much benefit to the rest of the

Thanks, Neil
