I think it would be nice to use the FEM code to make a "big book" containing all the documentation for the HDM project. Ross has some other highly-multiply-authored works that he has going on, too. All in all, it would be pretty cool just to be able to drop something derived from the FEM into a collection of TeX files and say "go" and have it spit out a compliation. But porting to the HDM collection would be a nice, simple, step. --jcorneli
