I was just thinking of that terrible scenario. You dropping off a server to be colocated and you've forgotten to set the IPs of the NICs. No problem if it's your own data centre but if you have to pay each time you visit your server, and you have no monitor or keyboard with you, it's a bit annoying. Many servers have KVM outputs on the front panel these days, I just thought it'd be nice to walk along with a laptop and a suitable interface and just plug it in. As "Space Cowboy" says, there must be a market for something like that. Oh and about the DRAC4 cards or similar (HP do one for theirs as well I think), yes I'd always recommend one - they work a treat and save on expensive, accompanied visits to your host's data centre.
