There is currently an IETF working group working on guidelines for URL registration. Registration of new URLs has to wait until this is completed. Your help in this working group may therefore be helpful to speed up the process. For more details on the WG, please see http://www.ietf.org/ and look for working groups in the application area. I have also forwarded this mail to the mailing list of that group; for future mail, please use only that list, and not the current uri list, which only deals with URL syntax. There is already a draft about the various things that have to be considered for a new URL scheme. But I can't find it's name at the moment, maybe somebody else can help. One point that is rather important for IETF process is that the specification (not only of the URL itself, but also of the actual protocol, as far as I know) is publicly available, and I don't know whether your registration process, which I just went through, would qualify. There are of course a lot of other things that need to be checked. I think it would be a good idea for you to start and try to write up an internet-draft about the URL, which later can become an RFC. This will help us to understand the procotol and the URL format and allow us to give you feedback.
