A common problem we have living in Thailand, and that is accessing some internet sites.
Have just found, installed and used a neat little program, basically a web front end to citrix. Install the server on the remote PC and then you connect with 2 levels of authentication. You can even set it so only certain phone numbers can connect.
Works like a charm. Had adsl on the server and the client was dialup, was alittle slow but usable. Can image if asdl on both, then would be very responsive. Remember though when using citrix, always make sure the server doesnt have any wallpaper as this dramatically slows down the link.
