Yes, both the SB-600 and SB-800 come with the AS-19 stand which has a plastic hotshoe and a tripod socket. This, of course, assumes you are going to be using it as a wireless remote flash with some other flash (SB-800, D70 builtin flash, etc.) setup as the iTTL master.
Another option would be to get a SC-17, SC-28, or SC-29 flash sync cord. The hotshoe on these cords has a tripod socket on the bottom, and you maintain full iTTL functionality while having the flash off camera.
I just picked up a couple of these "Justin" clamps (B/M 175F clamps)...very versatile.
JOBY is also coming out with a variant of their gorillapod that will have a flash shoe adapter on top. When it comes out, it might be a useful flash holding accessory as well. You can find a page on the Gorillapod here: http://www.joby.com/products.html
