Networking / Session ?s

So I did my first gig in a while where I had multiple programmers all on the same file with a Hog4. Is there anyway to set views / preferences per user or per console? I have a bad habit of changing my defaults as I program certain content / palettes, and it was killing my other user.

Second, can you assign more than one DP8K to the same net #? (I just wanted the 3rd and 4th DP to be a copy of the first 2 without having to patch all 4 in the patch window. I tried assigning them the same net number and it didn't seem to want to cooperate.

Last, what is the network speed required? 100mb or gig? I had one DP8K that did NOT want to connect the session even after a forced software reload. It grabbed the software just fine (via network) but wouldn't connect into a session regardless of net number and IP settings (DHCP or static) -- I was able to see the mac address hitting the network switch, so I know it wasn't a network issue.
