How to expose system variables to javascript like Meta-HTML References

Hi,

I'm trying to determine user's primary permission list using javascript and was hoping that '%PrimaryPermissionList' system variable would do the trick similar to what how Meta-HTML reference '%Appserver' works, but as you can imagine it doesn't work. Is there a way I could expose system variables to act like meta-html references?

My use case is as followed: I'm integrating walk-me with PeopleSoft and would like to use primary permission list as a segmentation for my users, where I'll be able to kick-in the walk-me process when user A has primary permission list of B.

Any other suggestion how to get to the primary permission list, or roles, or business units etc attribnutes of the user would be acceptable as long as I can get to them in javascript.
