That sounds like a good idea; similar to the isbn:// thread. It may be better to do p6rfc:// instead of rfc:// (incidentally, on a related note, the ability to link to IETF RFC's would be spiffy as well.. I'd write a HTCPTP client in Perl.. (Hyper-text Coffee Pot Transfer Protocol. 418 I'm a teapot))!
