They're kind of buried on both sites. On SRAM, you have to look in the Comfort Bike stuff. Here's the link:
http://www.sram.com/en/sram/comfort/...ubcassette.php The pict isn't verry good, because the view of the hub is covered by a cassette. Here's a better picture on the AE Bike site:

For Shimano, there's a Nexus link once you get to the North American Cycling main page:
http://bike.shimano.com/catalog/cycl...=1137090196889 As far as I can see, there are no disc brake versions of any Nexus hub (and, unfortunately not SRAM's Spectro line either).
The Dual-Drive requires SRAM's little 'click box' on the end of the axle to activate it, but that's far less hardware hanging out there than a derailleur - - and a person might even be able to fashion a little guard loop or 'skid plate' to protect it.
