FWIW, I emailed the sleepycat people and found that their pricing is
exhorbitant if all you want to do is some shareware thing that has an
embedded database.
Their reply to my pricing inquiry is below.
You can use an older version that was put out under a real
non-commercial license:

Berkeley DB is an Open Source product. You may download it and use it
at no charge, provided that you meet at least one of these two
requirements:
+ You do not redistribute it off of a single physical site.
If you use Berkeley DB on a Web server that is accessed
from many locations, but you do not redistribute the actual
code that uses Berkeley DB, you do not need to pay us.
+ If you redistribute your application, you make your source
code freely available.
If, instead, you want to redistribute in binary form the application
that uses Berkeley DB, you need to purchase a license from Sleepycat
Software.
The pricing for Berkeley DB depends on the services that you need. We
offer four different Berkeley DB products. All four are included in
the source code that you download from our Web site; we charge based
on the interfaces that you use.
The four different products are:
+ Berkeley DB Data Store: Intended for single-user, or
multi-user read-only, applications that don't need
transactions or disaster recovery.
+ Berkeley DB Concurrent Data Store: This product allows
multiple users to use the database at the same time,
with any mix of readers and writers. It does not
support transactions or disaster recovery.
+ Berkeley DB Transactional Data Store: This is our
enterprise-class embedded database manager. It supports
arbitrarily many concurrent users, with any mix of readers
and writers. It also supports transactions and recovery
from application, system, or hardware crashes.
+ Berkeley DB High Availability: HA provides single-master
replication with fail-over, and is built on top of the
Berkeley DB TDS product. Using HA, you can run multiple
instances of your application on different servers on a
network. All updates must go to the master server, which
distributes changes to all replica servers. Each of the
replicas can support read queries on the database. If
the master fails for any reason, one of the replicas is
able to take its place, and the application can continue
to run.
If you need technical details on which interfaces you're permitted to
use with each of the four products, you can look at our on-line
documentation. The supported interfaces for each of the products
are listed in our reference manual. Go to
http://www.sleepycat.com/
and click on the "Documentation" link, then the link for the reference
manual.
The prices for these products are
Berkeley DB Data Store $25,000
Berkeley DB Concurrent Data Store $40,000
Berkeley DB Transactional Data Store $150,000
Berkeley DB HA $300,000
These prices are for a buyout of the software. A buyout gives you the
right to embed it in your application and to distribute on any platform
without additional payment.
Annual maintenance pricing for each of the products is:
Berkeley DB Data Store: $5,000
Berkeley DB Concurrent Data Store: $8,000
Berkeley DB Transactional Data Store: $30,000
Berkelely DB HA $60,000
Maintenance provides access to new releases including bug fixes,
new ports, minor feature releases, and major upgrades. It also
provides business-day technical support by telephone or email.
Customers who need a higher degree of technical support can purchase
an annual premium support contract in addition to the maintenance
contract for the software. Premium support includes access to a named
engineer at Sleepycat for all questions, assistance with application
design and performance tuning, and a service level agreement with
committed response times for problems.
