I had not heard of DWService before, but they seem quite similar to TeamViewer.... that is, it looks like much of their remote control connection goes through their servers too. I did not dig into their site too carefully to see if they offer a LAN-only solution, but I didn't see anything in their FAQ or Documentation specific to LAN use.I have found this solution, has anybody experience with this method? I don't really know if this works over a server. If this is the case the solution is not good.
