there are nifty boxes out (have been for 8 months or so) that do
wavelength conversion. so the box-operator in the middle handles the
wavelength map, and users on each end can all use the same lasers
(colors). they were expensive at the time I looked but I would think
prices would have come down.
but yes, cheap tunables would be great.
