I have not looked over the license, but it would probably be beyond
what my time/skill level permits. Have you considered using r.in.xyz
(pre-filtering module) for your massive lidar dataset?

Also, by submitting that article to the list, I wasn't advocating the
use of TINs over grids-- I just thought it was interesting. I still
think that for most modeling operations, gridded data are the simplest
 to use / understand.

Cheers,
