Chris,
This is the first time that I have actually read what I have talked about for years. It obviously occurs on a peer to peer and not on a server/client.
It is never a good idea for someone to be using the computer that houses the database for a multitude of reasons:
1. What you just said. A workstation that is being used will require reboots more often.
2. The person using the computer will use valuable resources including RAM and processor.
3. The person using the computer is likely not a poweruser and ths could accidentally browse to the SQL Server files and delete them. Add to that going into the AC folder and changing things or deleting the AC folder.
4. The person using the computer could intentionally do the above.
5. That computer user could download programs or browse the Internet thereby increasing the chance of Trojans, viruses and other malware.
So, yes, put it somewhere by itself, preferably somewhere you can lock it.
