This is wrong (unless I misunderstand you). The Yahoo transport sends 
a <presence type="subscribe"/> to you - i.e. a presence subscription 
request. You then have to send back a <presence type="subscribed"/> 
(notice the 'd'!) to it. Then it should work.

That is propably because Yahoo-T is not subscribed to you, thus 
doesn't know you are "online" - and thus doesn't send online/offline 
etc. events to you.

Hm. The first entry is 'normal' for transports. It's used to allow 
auto-login to your Yahoo account once you send presence to this 
roster item (that is, usually on login)

1) The only way to find out if a roster item represents an agent is 
to match it to the list of agents returned from the server.

2) You do not need to send presence to it, though. Your client has to 
send a <presence/> tag (it can have a type/status/show flag etc., but 
*no* 'to' field)  once at the start if it wants to get presence from 
others (see the JPG for more info on this).
In general, sending a presence w/o a 'to' field means that everyone 
who is subscribed to you gets this presence from you - no need to 
iterate over your roster and send it to each subscriber manually.
