We use HP (OEM'd Advocet) KVM switches that have IP connectivity. The KVM switchbox allows 2 IP users running HP's Java client to connect to any server on the KVM switch. You have full access to the server during BIOS POST, boot-up, etc. We have 2 of those switchboxes and over 4 dozen servers connected to them.
Other manufacturers have IP KVM solutions. Check them out. Maybe they'll fit the bill for ya.
