Access control & Dirs outside of root? (ideas)

[lestat]

ok here goes....

My default host is setup with an index.php that sends referrers immediately to http://www.example.com/intranet. Intranet is access controlled by group. Been working great like this for long time.

I've created another dir that I would like the shopfloor to access internally (truly an intranet). http://serverName/shopfloor - yet another realm.

So far we have:
E:\websites\intranet
E:\websites\shopfloor

I'm curious how I can have /shopfloor/calendar/ItemList.php include() /intranet/calendar/ExistingItemList.php So far I'm not having any success, but I think thats because they are different realms

*OR*
Would it be better to create an item list dir outside the root, and just use an alias for it?
