[Beowulf] KVM advice

Do people here normally use KVMs for management of compute nodes or
forego those and either have a grad student with a keyboard+monitor on a
trolley or rely entirely on remote management cards and/or IPMI?
For those of you that use KVMs, what ones do you normally use?
I'm taking a look around at the moment and for 40+ nodes, KVMs look like
quite an expensive option. It's not clear either how well or which KVMs
can be operated remotely.
The scenario I have is that I have ~40 nodes in a room and I would like
to hook a KVM switch to all of these and be able to connect to the
switch from other parts of the building. I see Avocent (for example)
have some switches that kinda fit this model - but its not clear whether
the Avocents can be accessed over a standard Ethernet LAN, or whether
you have to run a dedicated CAT5 cable around your building specifically
to connect to the KVM switch.
Any experience from others on this welcome, I've mostly relied on
post-boot remote access, remote management cards and IPMI up to now.
