Also, keep in mind that you can turn on Logon Discovery in SMS 2, but if you don't modify the logon scripts (automatically or manually) then the clients won't run SMSLS.BAT, and therefore you aren't specifically impacting the clients yet.
The reason I mention this, is that you can enable Logon Discovery (which will install the neccessary files on the DC), then you can manually run %DC%\NETLOGON\SMSLS.BAT on your PCs via whatever method you choose (logon script, email link, pull...).
This would be sort of like running SMSMAN.EXE in the sense that you are "pulling" any installation, instead of "discovering" your clients. This is good, since SMSMAN has a Wizard interface (which is usually bad for users to see, but can be made silent).
