[jdev] Offline messages to users on transports

[Johan at bondeson.mine.nu]

Hi
I'm sorry if I'm asking stupid questions. I have looked around and not
found the answers so if you could tell me where to start looking it would
be great...

I was thinking about implementing a component in that can be run on the
server to let users of proprietary protocols that dont support offline
messages send them to me anyway. I would also like to be able to send
offline messages to such persons through the transports on the server.

Receiving messages from other clients while I'm offline I can achieve by
putting in an extra client on the server and then feed the messages back
into the server when I go online on my 'real' client.

But how should I do it the opposite way? How can I capture the messages I
send from my main client to the server, look if the user is online and
then delay the message if he isn't?

Any hints appreciated. Jabber is kind of a black box to me right now. So
where should I start looking?
