Chad Boeninger has a comprehensive post at Library Voice describing how to view your MeeboMe widgets while using Pidgin (formerly GAIM), thus obviating the need to have Meebo open in a website at all. I haven't tried Pidgin in a long time, but would LOVE not to have to have a web page open in order to receive chats via the MeeboMe widget, so I'll be trying this one out. In the comments, Caleb points out that "you can monitor MeeboMe with any XMPP client", which makes me think that Trillian Pro might be able to be made to talk to MeeboMe as well.
