Actually I forgot to mention.  Since we have different frequencies 
for the lasers, you and your peer would have to agree ahead of time 
and stock that particular frequency or "color."  IT's a major 
stocking nightmare especially for spares.  The real explosion may 
occur as tunable lasers drop in price that can allow 8 or more 
different frequencies.

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.
