is it possible to read variables from one application from another...
lets say you had an administrator page that was separate from the main site,
thusly a separate application name, but you wanted to see who was on...
could you actually read the mainsite.appliaction.user struct from the admin
site??
so far, i have used 5-10 min cached database queries to do this... but
wonder about the above... could have other value as well...
