I don't think there are any yet. From what I've read about 29ers, I'd be waiting for a 29er version of the Mavic EX823 before jumping aboard, ideally with 36 holes.
This is were my definition of true tubeless rims may fall down.
But the four main off-road rims from Stans no-tubes (ZTR Oly, ZTR 355, ZTR flow, ZTR arch) all have one 29er edition (All of these rims require rim strips to be run tubeless though). Thats 32H only. All of these rims were too narrow for my taste, except the flow. Which is 28mm wide, claimed to be 525g, and reputed to be pretty bloody bomb proof. Would have got some if the price was'nt so steep. The Velocity blunts I bought, were 1/2 the price and 50g lighter, with pretty much the same dimensions (and hopefully not made of cheese).
Bact to rim tape...
I have Velox on my fixed, but that doesnt see much rain.
On the utility bike (which sees lots of shite weather), I have cheap plastic stuff. This has perished in several spots, so I can comfirm that water does creep in to this area. I'll be replacing this with some more water resistant rubbery tape when I fit the winter tyres.
