...is an obvious issue, but is the group aware enough as to the size of
EOS and what direct support for its 'favorite son' will mean to KHOROS?

Translators are nice and necessary but whenever I try to say to someone,
"well, we can always translate it" I get looks that I don't approve of.
I'm actually working with someone here in translating datasets. Its a fine
thing but I want the Khoros applications to work with HDF data transparently.
Even the SDSs....actually, ESPECIALLY the SDSs.
