	Then perhaps the protocol goes like this:

Palm:    Hello, I am "Joe Bob", user ID 12345.
Desktop: Tell me more about your user settings. OBTW, the md5 hash of
         Joe Bob's password is "blah".

Then the Palm compares the given md5 hash to the md5 hash of its own copy
of the password. If they don't match, it refuses to talk any further.

	It's intentional in that before PalmOS 2.x (?) ReadDBList only
returned one database per call. The current code is backward-compatible to
the Pilot 3000, I think.

	IIRC each protocol gives its own compatibility version. That is,
at some point the Palm says, "I understand SLP up to version 2.0, CMP up
to version 1.1, and DLP up to version 3.0."
	I think an ideal solution would be to cache this information
somewhere (in the PConnection, I think), and use it to optimize further
calls.
	A slightly less ideal solution would be to declare that PalmOS 1.x
is no longer supported.
