Just adding something to wanton and navin's ideas if speed is an issue for VPN : I had used logmein.com (remote desktop) from here to access computer in Nepal. . May be you can install remote desktop software to your office PC and use it from Nepal. While connected with ethernet, logmein also has remote wake up feature in case your office PC goes to sleep or locked. My experience with 192kbps was not so good, but if you get 384kbps connection in Nepal, it might be acceptable.
