DH Jabber IM vs GTalk

I’m seriously considering moving my mail over to GMail now this seems to be the recommended approach. The newsletter seemed to imply that we could switch over to the GTalk servers rather than using Dreamhost’s ancient and flakey Jabber servers (although I couldn’t see an option for this in the control panel).

Has anyone tried this? Obviously the lack of gateways is a big concern. (They seem to only offer a AIM one and most of my friends are on MSN or ICQ). Has anyone tried a generic Jabber/XMPP client that supports adding external gateways? Can you use the (flakey) DH gateways?

(If I got a virtual private server would I be able to run some modern XMPP gateways?)
