No switch available with 10G-BaseT ports yet (there are not many 10GigE
switches to begin with). There may be new products by the end of 2007
with such ports, but I am not optimistic about general availability.
Today, it's CX-4 water hoses for clusters and LR fibers for general

20-25W is a lot. It's too much to land on a motherboard (that's one of
the argument against TOE) and it's way too much for dense switches. It's
going to get better eventually, but it's going to take time. I would
expect cheaper (quad) fiber solutions sooner than pervasive 10G-BaseT.
