Yes, that will work. It might be a bit easier of you use the tinc 1.1
prerelease, or at least use the "tinc" command from 1.1, so you can
add
and remove subnets simply by running:

tinc -n <netname> add Subnet x.x.x.x/32

If you are running a 1.1preX tincd, it will automatically get notified,
if you are running a 1.0.x tincd, you have to do "tincd -n <netname>
-kHUP" to have it update its Subnets.
