Well, I did mention it about a fortnight ago as a possible future 
contribution, but my efforts are currently on the VRML import/export 
followed by documentation and then the ssgStatistics module.  I think that 
it will be a fair while before I get to implementing ROAM for PLIB in my 
spare time!

That said, ROAM is only one of a number of continuous level of detail 
schemes for real time rendering - albeit a fairly oft-discussed one.  If 
you're thinking of doing some work on a CLOD system for PLIB, you might 
like to also look at some of the other methods of doing it - adaptive 
quadtrees, view independent progressive meshes and bin tri-trees, as well 
as simple distance based switching of meshes.  Ben Discoe's VTerrain site 
has a good summary of these techniques, with links to their original papers 
at http://vterrain.org/LOD/published.html
