Well, I do have more reasons to know the answer to this, as there are other executables and functions that I can't run on remote machines, as my login script sees all of the machines being identified as the Citrix server, itself.

Regarding the Windows Updates, I've used HFNETCHK and MBSA to identify missing hotfixes, but never to push them out. I'll have to look into that more. Any assistance that you have with that would be cool. Obvioulsy another forum, but cool nonetheless. However, I don't think either of these would help with non-networked users (dial-up and non-VPN). However, I could be wrong.
