We thank you for your thoughts.

Ahah, because the 'physical' server uses the URL to map to 'virtual'
servers.
You're right, the Rev 1.0 plan doesn't handle that.
E.g., We find that Yahoo.com gripes when referred to by a FUCANN alias:
Unknown Yahoo URL
or
The URL ``http://www.yahoo.foo/'' is not a valid Yahoo! URL.
You probably want the following URL: http://yahoo.foo/
Perhaps a future version will allow the specification of strings to
present to the
physical server, e.g.,
12.34.56.78 goodstuff.joe # FUCANN2.0: www.virtualname.com

208! (D0'h!)
One would need a GUI to get Joe Sixpack to even consider this burning of
brain cycles,
though he can be expected to grok the issue natively.
