He could contact Stephen at www.CableFreeSolutions.com and ask
about their FDX PtP products. I believe they have (or will have) a 50-60Mbps TCP FDX product available based
in the 5GHz unlicensed band.

Scott,
I think the biggest problem you will have when trying to replace a fiber line
will be half-duplex vs. full-duplex. They are "used" to
full-duplex... and 99% of the unlicensed equipment is only half-duplex. If you
move to Orthogon or something that will do 200Mbps half-duplex, you should be
fine... but you are talking a LOT more money than the 38ghz stuff. ;)
