The answer is Yes. We use GM5 on a peer to peer basis, we use the dbase file format, and once you install goldmine on a computer you can access the gm5 executable via a unc path - no installation is required on any other pc.
With other computers, It may ask you to supply the path to a dll file when you first run the gmw5.exe, the dll is also found via a similar unc path. (in a folder named 'install' I think)
for example GoldMine is installed on a PC named 'comm'
the path to the executable is \\comm\goldmine\gmw5.exe
you can shortcut directly to it from the desktop. Easy.
Good luck. HTH.
