rob:
I've made a proposal to add ByteString based datagram communication to Network.Socket and Network. Details are at:
http://hackage.haskell.org/trac/ghc/ticket/1238#preview
I rushed to get this done before I go on a trip tomorrow so I haven't completed testing and won't be available to discuss it for the next 9 days. As such, if discussion is needed, an extended deadline would be appreciated.
Testing windows is a bit awkward for me since I don't have a windows machine, so if anyone can test that platform I'd be very appreciative. I'll try to work through the problems I was having with hugs and test when I get back unless someone else wants to test it first.
Thanks.
I'd quickly note that you might also want to check the bytestring level stuff in HAppS/network-alt and in HaskellNet. -- Don
