Sorry, I'm replying to this mail despite the conversation having 
continued since, but there's a point here that I'd like to address.

I don't think this is true. Certainly there are use cases for IM outside 
those for email, but the reverse isn't really true (I'm not about to 
suggest we try and replace email with xmpp, but there's no reason to not 
provide an alternative) For people I have a jid for, I almost 
universally contact them with xmpp rather than email.

Well, I can't say I sit at my machine thinking "I'd love it if a Psi 
user contacted me right now to discuss X/Y/Z" but that doesn't mean I 
universally want them to not do so. Are these unwanted instant messages? 
I publish my Jid in various places -- if people contact me, is it 
unsolicited? Certainly I have no great desire to set up a presence 
subscription for a single conversation, but conversations without 
presence are not universally spam, or the suchlike.

Well, various others have said the same thing since this post was made, 
but I think it's better to just avoid this filtering behaviour.
