Then again it's possible to build terminal servers with ssh capabilities using off-the-shelf hardware and open source software for anything from $200-$400. Depending on how exotic you wish to get, however. For example; IBM have embedded RFB (that's something of an alias for VNC) in their management controllers for a few years now; these talk to the management processors (PowerPC 4xx family) in an xSeries cluster over an RS488 serial bus, which in turn are able to sniff PCI VGA accesses to give you true remote KVM. But I agree with the original point that was made about colo and remote management -- if you can't fit remote management into a colo situation, your management costs will increase far more if things go wrong.
