I had this really odd thought that it might be possible to do a decent
RPC setup using only the HTTP headers of a request.  They are there for
meta-data anyway, and any unknown ones are ignored.  I gave it a try and
was able to get decent responses from both sides.  It seems rather
lightweight and good enough for most quick requests.  It''s kind of like
a weird one use shared hashtable.
Question is, how many things would this screw up?  It''s part of the
standard that you can add headers if you place an X- in front.  Anyone
have ideas as to the usefulness of this approach? My gut reaction says
it''s going to interfere with some of the load balancers and defense
mechanisms.
