Experience, no. However, logic and systems behavior dictates
that system load is dependent on use thereof and not total
number of user accounts on the system. We have an office
environment where the Qube is DNS, DHCP, SMTP, POP, HTTP,
FTP, and Samba server for about 85 people. They're usually
*all* here, and the Qube (64MB, 13GB) doesn't even blink.

If you estimate that the total load will be less than 150
*concurrent* users, you should be OK. Also think about the
type of tasks that they will be doing. Are they CPU or RAM
intensive? I'm sure you can take a Qube apart and add
memory... as a matter of fact, I'm thinking about buying a
16MB Qube and adding memory for the house. But the CPU is
a fixed limitation and if the load goes berserk, the Qube
will crash.

My guess... you'll be just fine.
