Associating a 'buddy icon' / avatar with an XMPP App Engine 'bot'

[swinton]

This has been asked before but with no response, so I thought it worth asking again.

Is it possible to associate an avatar with my XMPP bot? It looks as if this should be possible, according to the spec, but I've no idea how to implement this in App Engine.

Any pointers?

Thanks,
Steve
