Its a network directory service
PAL has been tossed about in the university setting for a while. The technology does sort of exist with 10.2 server. You have a user log into the LAN network mainframe and thier 'user' directory is available. So ANY Mac (in some cases PC) they lgo into has their docs, email, boomarks, etc. As long as its on the campus network.
PAL is the long touted software that the university reps say will make it easy for faculty and staff to have access to thier work files while at home, from a Mac or PC. So, if they use a Mac at work and a PC at home, they can still sync files, bookmarks, email, etc. I am told its going to be seamless, and work with win 2K and XP pro as well as 10.3.
It can be configured via an internet storage server a la .Mac for home users, or a special server for business, and education customers. So, in the case of my university, they would have a deicated PAL server running OS 10.3 server to host the files for all the clients.
What I have been told is oldish news, and they are not hypeing it up, as much as offering a solution to an age old problem. I am glad to see its nearly here.
