AFAIK, Serial over LAN (SoL) is a standard function of IPMI and the 
likes. Wikipedia says that SoL is availabe since IPMI version 2.0 [1]
On my Intel Xeon based server (which is approx. 10 years old), I can 
access Xen's serial console via SoL. I successfully tried Intel 
Manageability Commander and Mesh Commander [2].
