I want an im:// protocol handler installed by [my favorite IM application]

Note: this entry has moved.

I'm SO used to typing WinKey + R, mailto://[address], that I seldom open Outlook's main window to send mails. Even more, Gmail (I don't remember if it was google desktop) can take control of the protocol and open up its compose webpage. 

I started doing the same with Skype calls by using the same combination but with callto://[user] (if only my buddy partner would have a shorter alias instead of callto://victorgarciaaprea ...).

Now I only need im://[hopefully short buddy alias here] (guess which is my partner's :S:S:S).....

And what about post://[my new post title here] to fire-up the default weblog post authoring app? (even if it's openening your blog engine webpage...)
