Source for DVI/USB KVM switch, cables

Similarly:

Can anyone recommend an industrial strength KVM rig for a lab
environment of 400+ systems ?

One of the really nice features would the capability to ssh/telnet to
the different ports in order to control an automated installer
environment.

The problem I'm trying to solve is this:

 We want to have our product's install be run automatically such that
 when a system is automatically rebooted, it uses PXE and DHCP to
 invoke a tftp transfer of the ISO image which the client then boots
 and installs off of. 

 Given that the installer usually requires human interaction, we need
 a way to "drive" the install process from an automated test
 harness. Since the system isn't on the network during the install
 process, we'll need console access, hence the need for a KVM
 infrastructure.

Any ideas about this would be gratefully appreciated.

Thanks.
