I haven't seen TOO much discussion on HTTP here (is there another mailing
list for this? I can't even find the HTTP/1.1 spec...) but looking at the
1.0 spec at CERN indicates there are alreadyt proposed methods "CHECKIN"

I'm specing out).

There's a hypermail archive at
and Nick Arnett's similar archive which I have embarrassingly lost the
URL to.

I don't know how much the CHECKIN/OUT methods were discussed, but not a
whole lot was talked about the LINK method, which I'm looking at very
