I've gotten some nibbles from at least 4 people on the upstreamer. That isn't all 7 of you out there but I guess this will do :)
I'll start on it this weekend or sometime early next week. Hopefully it will go fast as I already have the FTP code.
Gary Burd suggested a combo of ssh, rsync and a crontab entry. It looks like you can install RSync on windows if you try hard enough. However, I don't have that much control over all of the machines that I want to upload to, so this looks like a non-starter -- at least for me. Getting a more secure connection would be nice, though.
I also was thinking about taking advantage of the shadow copy stuff in XP but it looks like you need to sign an NDA to get at that SDK. Oh well.
