Hello
I have a similar problem, i have a database of over 6000 files which i need syncronized between currently 10 computers. some of my files are big (a few hundred MB) and others are small and the system i use works flawlessly. if the DAT and .reg files you export are under 2GB you can use the same system as me. It works in the background with no need to even check it, it has automatic syncronisation, and will syncronize from any machine online. I researched many methods before i chose this one for my needs, and this one is brilliantly simple and fast.
