FWIW Yeah really in BeOS we have them mapped as application/x-vnd.Be.URL.foo and that's what we use in Haiku as well.
I suppose we could push Haiku to switch to this supertype too...
Does the IANA actually allow vendor-specific supertypes ?
Nice to see we had it right ;)

I don't see what's wrong with this...
"BeOS did this 15 years ago" also with applications, they all have a mime signature anyway ;-)
For example the default browser is the preferred app for text/html, same for text/email :
$ setmime -dump text/html
/bin/setmime -set text/html -short "HTML File" -preferredAppSig application/x-vnd.Firefox -sniffRule '0.40 [0:64]( -i "<HTML" | "<HEAD" | "<TITLE" | "<BODY" | "<TABLE" | "<!--" | "<META" | "<CENTER")' -extension htm -extension html
$ setmime -dump text/x-email
/bin/setmime -set text/x-email -short "E-mail" -long "Electronic Mail Message" -preferredAppSig application/x-vnd.Be-MAIL

In Haiku /bin/urlwrapper accepts http: and calls wget, which can be useful as default when no browser is installed...

urlwrapper here starts Terminal with the corresponding command for ssh:, telnet:, sh: (with a warning :p) :-)
I even wrote
which accepts git: svn: and friends and asks you where you want the sources checked out :-)
