I've added columns for InterBase and DB2 to my SQL comparison chart, and
I've run into a stumbling block.
I can't seem to figure out if you have to buy InterBase or not.  They're
selling boxed versions and client access licenses, and then there's the
server and client sourcecode right there for downloading under the IBPL.
Any Borland / InterBase fans here that can clear this up?

For the curious...

Info contributions and updates welcome.  (Especially since somehow my
site managed to leak out to search engines.  Something I never
intended.)
