I don't have any of these shared configs, but they exist.
I'm not clear on how well they work. obviously IPMI is low-traffic,
so I would think a shared config could work well.

switch ports are cheap. if yours are not, you're doing something wrong.
especially since IPMI is always 100bT (afai seen) so we're talking any
old commodity thing: isn't $2-3/port worth it?

I've never used/seen a real kvm-over-ip (have some kvm-over-cat5 though.)
