Ahh, sound & video.  I can see that posing a problem.  The suspend/resume session should not be a problem for things like VNC.  In fact, you could have a whole bunch of clients all watching the same VNC session simultaneously, or you could click the checkbox, "when a second session connects, terminate the first one."  Which just limits the number of simultaneous different clients to 1.

VNC might not do well at supporting audio or video, but I'm quite sure NX does.  And Exceed onDemand.  And GoGlobal.  (All commercial products.)  And Citrix ... whatever their product is called.

The world of resumable X sessions might have improved in recent years.  You might search around for that kind of product.

Also, now that I think of it, the only reason something like VNC wouldn't support video would be if the video is going through the video card, in which case, probably nothing can possibly support it.  But even if VNC does support the video, it's likely to be very high bandwidth, and it might perform poorly.  Products like NX (I'm naming NX specifically) have more intelligent algorithms that send rough images first, and sharpen as bandwidth permits, so if you don't have enough bandwidth, you'll just get a grainy result instead of a broken result.
