Island, are you saying that when you travel, you're already establishing a VPN (secure "tunnel") connection into your private network and your remote desktop is locking up? If so, you might want to set up a continuious ping from a CMD window to say a router on the inside (or anything really, but not the PC you're remoting to) and see if that's still working when your remote desktop "locks up". If the pings stop too, then you're looking at a VPN networking issue but if the pings are still getting responses, then you're dealing with a "client" related issue. Heavy graphics shouldn't matter on a VPN tunnel (from a networking perspective) if everything is "healthy".
