My understanding of  LVDS is that it is good only for distances measured
in inches (or centimeters), such as the connection between scsi adaptor
and peripheral, and video card and monitor (primarily LCD monitors).

I haven't heard of low voltage differential signalling used for long
distances and I assumed it was because a low voltage signal will be
swamped by emi/rfi/etc over longer runs.

What are you trying to accomplish?  Do you need the high signalling
rates over long distances?
