Or in serverless mode you could automatically return the disco#info in
the response, like so:
<stream:stream
xmlns='jabber:client'
xmlns:stream='http://etherx.jabber.org/streams'
from='[EMAIL PROTECTED]'
to='[EMAIL PROTECTED]'
version='1.0'>
<stream:features>
<starttls xmlns='urn:ietf:params:xml:ns:xmpp-tls'/>
<query xmlns='http://jabber.org/protocol/disco#info'
node='some-node-here'>
<identity category='client' type='pc'/>
<feature var='http://jabber.org/protocol/disco#info'/>
<feature var='http://jabber.org/protocol/disco#items'/>
<feature var='http://jabber.org/protocol/muc'/>
</query>
</stream:features>
But that doesn't solve the problem of prompting the user when someone
wants to open a stream (however, the interface could prompt the user
only if the contact goes beyond the disco stage).

I like that less well, but I'm not sure why.
