I think the use of the ?? would not be a good URI scheme. However, maybe we
could simply make the VFS parameters unique. For example add vfs. in front
of them. 

For example, 
http://www/path/cgi-bin/send.pl?FILE=ABC&TYPE=PDF&vfs.proxyHost=proxy.host&vfs.proxyPort=8080

or 

ftp:/fremantle.org/file?vfs.passive.ftp=true
