Top-posting to myself, so sue me... :p

I realized that I never shared the cost-effective device that I settled on 
for this.  In the past, I remember contacting Paul Vixie directly since 
he was a BSDi (now FreeBSD) diehard and he'd written some open source 
terminal server software.  He was very helpful, so I decided to hit him up 
again...

He said that ISC is using these devices and they have been working well:

$500 for 16 ports.  It's basically a box with a bunch of USB->serial 
adapters and a hub.  In FreeBSD 5/6 it's totally plug-n-play.  In 4 it may 
or may not be depending on the chipset.  Mine required a manual backport 
of some driver code from 6, but it was very simple for a non-coder like me 
and I have the info saved.

So hats off to Vixie, this was exactly what I needed.  Combined with 
conserver.com, I've got a really nice console server that's secure, logs 
all console output from all the servers, and has been very reliable.  This 
box takes standard DB9/DB9 null modem cables that can be had for about $2.

I'd also recommend looking at the entire USBGear serial line, there's some 
really cool stuff there if you need more than 2 serial ports:
