New Tech - What is RCA's VPORT?

JoshRoss asks: "I was looking at the televisions on Bestbuy and I noticed that the RCA televions have a new 'feature', the VPORT. I looked around for information about this and just found RCA press releases for their XBOX READY logo. What is the difference between the VPORT and S-Video?" Is it just me or are others disturbed by the fact that the VPORT is touted as an X-box only feature as opposed to a console feature, although I must admit, it does make sense from "product synergy" standpoint as mentioned in this interview. Does anyone have any details on what this type of port this really is. Will other console systems be able to take advantage of it?
