if u have a network of pc's, try using the remote assistance between 2 of them. nice transfer rates and graphics are loaded much faster to the point that it is acceptable to the eye and even the mouse movements are just about in sync with each other.
ive used it also though net connections like cable, dsl, t1 etc. it sometimes is still laggy for each end, but having either one is the minimum desirable and not dialup. of course higher speeds mean better on-screen performance.
