@Gavin: I don't see the sense of a Bitcoin MIME type. A URI scheme describes a resource. A MIME type binds a document type to a handler. Implementing a "click to send Bitcoins" capability using a MIME type would require that the website on which the payment link was embedded send a new document to the client browser. Seems needlessly complicated to me.

But a bitcoin: URI has problems, too:
1. It is hard to implement-- every browser has a different way of registering protocol handlers.
2. If you don't have the protocol handler installed, clicking on the link doesn't give you any help on what to do to make it work. (try it here)
3. Looks like some software (like this forum) don't like bitcoin URIs: Donate to the Faucet (that URI is bitcoin:15VjRaDX9zpbA8LVnbrCAFzrVzN7ixHNsC, the forum software is truncating it and adding http://).

Implementing something that won't even work on our own forums would be a bad idea, in my humble opinion.
