[hybi] Serf support for BWTP

[Justin Erenkrantz <[e-mail]>]

Hi hybi@,

Out of some stuff that's been done with CREST [1], I got pointed at
BWTP and decided to implement it in Serf [2].  A colleague of mine at
UC Irvine is implementing BWTP with PLT Scheme for some CREST stuff
he's doing.  (In short, CREST would benefit from having an async
protocol.)

If ya'll haven't followed the Twitter conversation between me and
Hixie over the last few days, I've pretty much come to the same
conclusions regarding "Web Sockets" RFC that Greg Wilkins did much
earlier.  (Kudos to Greg!)  I guess that Hixie has tried to write his
RFC drafts in a way that stresses one particular way of writing a
client - but for a pure async client library like Serf, the
description in the RFC is pretty impenetrable...and, in my mind, not
very helpful when it comes to writing an independent implementation.
So, I found BWTP a lot easier to implement...and so I did.

The BWTP implementation in Serf isn't perfect and there's probably
more to do, but it'll suffice for now.  Though there do seem to be
some errors in the BWTP RFC, but I'm not sure if Greg is updating the
BWTP RFC drafts or not.  If so, I'm happy to post about those apparent
errors as well.

Anyway, Hixie asked that I subscribe/post to the IETF list, so here I
am.  =)  -- justin
