Why not parse it literally?  For instance, http://www.ufp.org
would imply TCP, dest port 80, and host www.ufp.org.

For ping, that would imply that I want to test the three-way
handshake on whatever is listening on port 80 at www.ufp.org

For traceroute, I want to send a series of TCP SYN packets to
www.ufp.org, port 80 with increasing TTL values.  Perhaps this
would be a way to test connectivity to a service behind a firewall.
Perhaps this would be just another DOS tool for lamers...

For email, this would not make a lot of sense.  Should my mailer
try to connect to port 80 and start with "ehlo www.ufp.org"? 
After all, I *DID* use the http:// prefix...

Using "ftp mailto://postmaster@ufp.org" could imply that I want to
send a file to someone via email.

On second thought, it looks like most Internet apps would have to
be rewritten to understand this new functionality.

In this case, mutt should do an HTTP request to port 80 at www.ufp.org,
grab the home page, and put it in your inbox :-)
