Running a Feature Pack Package at Login

I would like to run my SMS Feature Pack 'packages' at computer login perhaps through a login script GPO. It seems like I should be able to do this without advertising it but I cannot seem to see how.

From the microsoft.public.sms.admin newsgroup
This is a bad idea. The packages are designed to be sent out with SMS and you will have no scheduling or reporting if you don’t do it that way, you would in effect have to go to every desktop and check. Microsoft seem to strongly recommend against this.
