I have used this product (SourceOffSite) and it is quite good. At the time I used it (early last year), I believe it required a web server with IIS. It was also a little deficient in features, but it has since been substantially improved (if their marketing mail is to be believed <g>).

It runs as a service on your NT box, and you set parameters for where the VSS library is (it's an add-on to VSS, not a standalone VCS) and who the users are. It also gives you a data encryption option.

Basically one of us needs to be able to check out a form or report and if the other person is working on it, then the system needs to notify them that it is already checked out. We are both maintining a copy of the development directories on our local workstations.

>>I've thought of something as simple as using WS_FTP Professional, which checks to see that files are synched in two directories, and FTP's the changed files back and forth until the two directories are in sync. This would work fine for a single person; but since there are two of us, we need to have a slightly more sophistiticated ability to replicate the files.
