ayup. i've seen a few SS fullys. most will require a derrailleur type tensioner with two pulleys, as the simple single pully tensioners ala surly and so on won't be able to take up near enough slack to account for the chain grown as the suspension cycles through its movement. the two pully systems keep tension on, and keep the chain in better contact with the rear cog vs. the single pulley versions.

what'll work here:
your old rear mech, or a new one if you want, as these will take up the most slack of the suspension movement.

these two may work well too. at least i know the rohloff one does; i've seen it in use with a few of their hubs.

or, its doable on a fully frame with no chain growth if you use a singleater style tensioner.

i'd think it'd work on many fully frames, depending on the length of travel, and leverage ratio. only so much slack the things will take up. you would probably have to run an outer bash ring, and something inside of your front ring at the minimum to prevent derailment up front.
