ok. i don't use VASP and never used those plugins, so i cannot
comment on them. they look a lot like they are modeled after
the cubeplugin. does that mean, you are mostly interested into
making gridded data readable? have you checked, whether this
is stored in reciprocal or in real space?

you don't have to compile VMD to compile the plugins. still
with over two years since the last release you don't want to
start working off an antiquated version of the code.

all you need is to apply for read-only cvs access and that
is usually done very quickly.

the main documentation is (in) the source code. the changes
are incremental, so old ABI plugins should continue to keep
working, but there are several exciting new features like
the ability to (optionally) store velocities and complete
wavefunctions, if projected on atomic orbitals. however, that
last part is still being worked on, so it is in a bit of flux.
there is a plugin for gamess and i'm currently working on
plugins for gaussian and CPMD.
there also is a project underway to have all output redirected
to a console log window which requires some (transparent) rewrites
of the plugins (they still compile for 1.8.6).
cheers,
axel.
