I'll get back to GP later. Or Sandeep is the master.
As far as RDP goes, I personally witnessed Adam Lauer to nine computers in less than 12 minutes minus the remaining install.
RDP 6.1 on all WIN 7 computers (on XP as well). Of course, RDP on the computer you are installing from (not necessarily the computer with the installer) should have all of the computers with Fully Qualified Domain Names (computer.domain.local). You can use IPs, but FQDNs are (can explain later).
Remote to Computer 1, browse to installer, start install, remote to computer 2, browse to installer, start install, etc. This process should take less than a minute per computer = 9 minutes. Go back to each computer remotely and go through the OK, OK, Yes, etc. until it installs by itself. Go to next computer = 3 minutes. Of course, if you are uninstalling first that will take about twice the time depending on what setting Your Installer 7! is set on. Read Revo for everyone else. I suppose you could have a script, but I don't have one.
For another reason, use the FQDN.
