get user account type within IE

[fltcpt]

Hi,

Any body knows how to check user privilege with Javascript
on IE? User privilege as in whether the user is running
IE with admin or limited user priv. I realize Javascript
is cross platform but is there some tricks there? Say
using javascript to do something that requires admin
privilege etc.

Of course I prefer the method to not invlove any
warning messages or extra download/install
for my users...

Thanks alot, anything helps
