Hi Scott,

I do believe Serendipity Database--Binary (SDB),
<http://wecode.org/serendipity/>, is the closest current example of what
you are looking for. SDB is a hierarchical database implemented as a
Revolution stack. The search algorithm is binary, not ISAM, but can
retrieve one record out of 43K by key value in <l second on a medium-speed
G4 iMac. The design includes room for a B-Tree or other ISAM index; but I
get adequate performance from the binary structure and don't plan to pursue
other indexing schemes for the foreseeable future.
SDB is open-source and royalty-free. The download includes sample
databases and front ends, db utilities, a reference manual, and RAD tools.
