Growing on trop. hardwood (Ipe)?

[tropterrarium]

I got a bunch of tropical hardwood scraps of ipe (Tabebuia, Bigoniaceae): 1x6, 2x4, 2x2, 4x4. Has anybody mounted on it? It is very dense and heavy, but should be more rot-resistant than other woods. Given that it is so hard, roots can certainly not penetrate it, but I wonder whether roots can attach to it. It may work ok for species with thick roots (Epidendrums, Brassia), but not for more dainty rooted groups (pleurothallids). Any experiences?

Otherwise, I've mounted on natural branches (manzanita, citrus, hibiscus), wood slabs (pine, redwood, oak), cork, some treefern.

I grow in terrarium and GH, intermediate temp with RH around 75-80%.
