We have pretty much 100 client seats scattered over sites in Morocco and Ukraine connecting into a Foxpro database in the UK using a Remote Desktop connection on a VPN and the performance is pretty good. Except for when Moroccan Communications lets us down!!!
You could have a look at Terminal Services / Citrix but I would have thought you would get the same performance measurement that Remote Desktop.
Database replication?? Or am I opening a can of worms!!!
Hope this helps
