I would not suggest installing RTCOMM unless you are an experienced user. It breaks functionality of the Application Manager and not all features are implemented yet (such as adding new friends). When it is installed, it is very simple to use. You just have to go to your accounts portion of the Control Panel and create a new account. You will see the various account types have grown quite a bit. Not all work correctly yet, apparently. Yahoo does not appear to work as far as I can see (or it can be the same issue I have on Jablet with really old accounts made back when everything was case-sensitive).

Jablet is not going away.

John: Sometimes AIM ignores status requests. This is a problem even in the official client, just that the average user never notices it. I believe that the IM Gateway may not support invisible mode, but do not quote me on that. I have also had the problem with messages not showing up on AIM, however it was extremely rarely and showed up when I was directly connecting to AIM through Kopete, so it might be a server or protocol issue. If it keeps being an issue, let me know and I will push it towards the IM gateway guys.
