I think the easiest approach is to present it to the end-user as a set 
of Jabber hosts, even though internally it's all one component. Then the 
user can register with msn.mydomain.com and yahooim.mydomain.com as with 
any other gateway, and the JIDs for the foreign users will be like 
billg at msn.mydomain.com .

As for the login details, these are generally provided when registering 
with the transport and stored by the transport against the user's JID. 
The transport then subscribes to your presence so that it can see when 
you're online and do a login with the stored credentials. Obviously you 
should only use gateways you trust, since they will have access to your 
account details.
