I went down to the local lakeshore and scavenged some driftwood, as well some beautiful water-worn bricks. Soaked it and boiled it, but still had to tie it down when it went in the tank. So far, everything is going swimmingly, and I'm slowly stocking my tank. The wood did grow some fungus at first but it didn't seem to affect my tetras or BNPs, and has now cleared up nicely.
My advice is to make sure the tank is well cycled (should go without saying), and when you add fish, add only a few at a time with a hospital tank ready. That way if there is a problem, you've got a back-up. Also be DILIGENT about water changes. For the first month or so after my tetras went into the new tank I changed 30% of the water every 2-3 days just to be safe.
It can be done, but prepare for the worst.
