Yeah, you're right, ccd is probably his best bet if he must use an IPC
for a newsspool. He might consider getting a better sparc though if he
wants to get decent performance out of this. I don't know how many
users he plans to run off of it, if any, but it's not gonna be a speed
demon by any means. Old ss5/10/20 machines are so cheap now! Hell,
even some of the Ultras can be had for PC-like prices. It's incredible.
