The easiest thing when using VSS in this situation is to just get a copy of the source file you made changes to...copy it to you development machine that has access...check the file out and then back in. This will post the new file rather than the original.The best solution by far is moving to Team Foundation where you can connect using a software VPN (or hardware) and make ths changes real-time. I have been on a trade show floor before, made changes through a software VPN on my laptop, and the updates are already in the source control and I never have to think about it again. Food for thought
