(1) There was no Intranet module in AD's ACS 4.x (IIANM, it is in 5.0-java).
(2) It cannot -- there was a lot in ACS Classic's (3.x) Intranet that is entirely absent in OACS 4.5 OTOH, much of what is in OACS 4.5 can be very wll used to build Intranet in the most efficient way.
If you search this thread, you will see that there were suggestions made of porting 3.x Intranet to OACS 4.5, however status of those is not known. I did try to poke around the thing and see what could be done, but, as usual, too little time to really do anything -- did not get anywhere.
