irc: message notification when away (xchat)

We are using IRC in my office for internal communication. It is very impractical to disconnect/reconnect every time I leave/return to my office. Therefore I leave my irc client (xchat) running all the time. But lets say, I got stuck in a meeting, and I have my laptop with me. Is there a way to check whether somebody has sent me any message ? I know, that I cannot connect from second machine under the same account. Or perhaps would it be possible to forward a copy of every irc message on my jabber (which I can then check on my laptop) ? I would not mind, if I got all messages on my jabber, regardless whether I am away from my office or not. I hope my question is not too vague. I don't know where to start looking. I would appreciate any comment/suggestion.
