This is also similar to the facility in IE of "pluggable protocol
handlers"; for example, if you install Napster on your machine,
nap:search?artist=Goodie+Mob&title=Soul+Food becomes a usable URI.  In
this case the link causes Napster to load with a list of all nearby
locations for that song.  Sean makes a good point -- it is crass to make
a new scheme for something that is already supported by an existing
scheme like http:// or news://.  For implementing in IE, see

Protozilla [1] is a plug-in (not strictly... I think they call it a
socket adaptor or something) for Netscape6 that allows one to
associate certain protocols with a particular action on ones computer:
just what you've been looking for, according to:-

[[[
The two on my personal to-do list are mid: and irc:.
]]] - http://www.w3.org/Addressing/schemes

More information about Protozilla is available from [1] which I have
pointed out numerous times before after being introduced to it by
Aaron (who will almost certainly have sent a similar letter to this by
the time I'm through writing). Downloads [2] and examples [3] are also
available. Protozilla also carries with it certain disadvantages: it
makes it way too easy for people to start using URI schemes as
redirects, e.g. myscheme:ABC could be used to reference
http://www.example.org/example/ABC - I can see some of the Wiki people
starting to use wiki: already :-)
