I'd like to run the following around, and if there is
reasonable consensus, I would be happy to write a 
more complete description.

First, let me note that there are two distinct 
parts to HTTP - one in-band, and one out-of-band.
The in-band are the HTTP commands, the out-of-band
deals currently only with TCP, hostnames, and the port selection.

A modified version might look like:

	(in-band-protocol):[out-of-band protocol]//loc-info/file-info

where loc-info is parsed according to the out-of-band protocol type.



The default currently would be presumed as 

	out-of-band protocol 	= TCP
	loc-info		= IPv4 DNS name or IP address,
				 and TCP port number

The idea is to separate the URL as follows:

	what to say:over what connection//where to talk to/what to get

Note that this is a URL mechanism only. Is this what you're looking
