Greg isn't but Schlumpf is. 'link'

Kris Holm and Schlumpf will be releasing a splined geared hub
eventually.

I had quality control problems trying to mass produce the hub overseas.
Florian Schlumpf was bugged by enough unicyclists that he applied his
PowerDrive technology to a unicycle hub and eventually mass produced a
frame/hub set. Florian is a much better mechanical engineer and
machinist than I am. The product that he makes is superior in many ways
even to the hand made hubs that were my prototypes. He makes case
hardened parts for greater strength in a smaller package, his parts are
machined to tighter tolerances, and his design is shift-on-the-fly.

I hope you are still interested in geared unicycles because the more
that are purchased the further the technology will advance. Pete
Perron's PurplePhaze and OuttaPhaze projects are now produced by Dave
Stockton. This is a Coker only design as far as I know but, although
fixed gear, it is simpler and more flexible than the internally geared
hubs. There are only two internally geared Cokers that I know of. One
of them Dave and I built up for Kris Holm. The other was made from a
hub Steve Howard reworked for Mike Scalisi. I think Florian offers or
plans to offer a 36" internally geared version.

Interest, exposure, and marketing pushes the technology.

The schlumpf is a very nice piece of equipment.

Florian does offer it in a 36", but not as a whole unicycle. There is
one other internally geared 36" unicycle that I know about and that is
a schlumpf 36" that is owned by Hans, who was on the 'Laos tour'
(http://laosunitour.org/equipment_set-up.htm).

There are a couple of geared 36" wheels in the UK, Roger Davies has one
and Richard Lewis (loosemoose) has the other.

Although Roger was saying at the weeknd he might be going to build his
hub into a 29" wheel instead, as he doesn't reckon he's faster on the
Schlumpf coker than on the normal coker, I think he doesn't like the
bruises off the frame cos he's got short legs either, apparently it's
particularly hurty when riding muni on it.

The Schlumpf unicycle has a lovely hub, but the rest is poorly
designed. The new kh/schlumpf looks like a fantastic product, because
it combines the KH experience with making unicycles, with the Schlumpf
experience of making gears, so should hopefully be something pretty
special.
