OS X Login Script Help Needed

Question

I think I'm posting this in the correct location.
Here's what I have. I'm trying to get past the issue with Adobe Reader not working under network accounts. The problem is that when a network user logs in and tries to launch Reader it crashes almost immediately. I've found that if I move the 9.0_ppc directory to the /Users/Shared directory of the local Mac and then create a symbolic link to it in the ~/Library/Application Support/Adobe/Acrobat directory that it works just fine under the network accounts. Problem is there are too many accounts to do this to feasibly.
So what I'm trying to figure out how to do is create a login script that will apply to all users. This script should automatically delete the /Library/Application Support/Adobe/Acrobat/9.0_ppc directory and replace it with a symbolic link to the /Users/Shared/9.0_ppc directory.
Seems like this should be a relatively easy task but has proven to be quite challenging.
My server is running OS X Server 10.5.8 and my workstations are running 10.4.11

The magic word you need:
loginhook
This is a place where you can attach a script as the user logs in. You are still the root user for the duration of the script, but immediately after the script ends you become the logging-in user.

One "famous" loginhook for moving user caches off the Server and onto the workstation's Hard drive is described in this mailing list item. If you lift it, note that there is a space missing in one line of code, but i think a later reader comments on that.
