The way that I've handled it is to use 'user at host' as the key for looking 
up stored credentials.  Although changing it to use 'user at host/resource' 
as the key, that approach would mean that the user would have to resupply 
credentials if they connect using a different resource value (perhaps this 
means different client, perhaps it means a different instance of the same 
client).

Peter Saint-Andre can probably comment which is the intended approach for 
JEP-100.

The cruftyness comment is because I don't bother to copy the resource 
value from the requesting client to the proxied user at host.  Eg, if you 
start talking to the gateway as 'user at host/Gabber', the proxied connection 
is 'joebloe at someotherhost/gateway.processid.timevalue' .

I'm not sure I follow you.  I'm passing from the component to the user:

 	<iq from='componentname' to='user at host/resource' type='result'>
 	   <query xmlns='jabber:iq:register'>
 		<instructions>
 			All of the requested fields must be filled in.
 		</instructions>
 		<username/>
 		<password/>
 		<domain/>
 		<server/>
 		<port/>
 	   </query>
 	</iq>

With Gabber, I see a window that asks for:

 	Domain:
 	Password:
 	Server:
 	Port:
 	Username:

With PSI 0.9.3, I see a window that asks for

 	Password:
 	Username:

Debug on PSI shows that the packet is received as quoted above, so its a 
bug in PSI.

However, if I register with Gabber, I can still use the gateway with PSI.
