our experience is different. We've had way more trouble with serial port
concentrators, cables etc. than enet switches. Overall the scenario you
describe would not work well for us. It does work for many people however.

This is an important one. You're right here. But rather than go with the
serial port concentrators we're probably going to put console messages out
over enet.
