Yes. Snodgrass (now email@example.com) has developed a public-domain
variant of his IDL toolkit, now called Scorpion. John Nestor of
Persistent Data Systems has two IDL variants: Mini IDL (described in )
and Professional IDL. Both are relatively inexpensive (about $50 for
Mini IDL) and are probably much more thoroughly tested than even a
quite competent academic like Rick would have done. Persistent Data
Systems also has an IDL-based persistent data store called IDB; it's
fairly expensive by my standards, but quite impressive.
I continue to work on my own variant, but am unlikely to make it
publicly available for at least another year [unless a Fairy Godmother
shows up to buy me a good systems programmer or two].
There was once an IDL newsgroup, comp.lang.idl, but lack of interest
and the arrival of a completely different language called IDL
(Interactive Data Language, I think) killed it off.

The original UNC toolkit (described in ) is available through
UniPress for mucho bucks. Ask Snodgrass for Scorpion instead.
