John,

if you do have the option of using a local area
wireless network (i.e., you're guaranteed to always be
within range of an access point), I'd definitely
consider that as an option, for a number of reasons:

1. Crunching through a large database is much faster
on a backend server than on a Palm

2. Getting a wireless TCP/IP connection to work on a
Palm should really be not that hard.

3. No 'maintenance' (software or data updates) for the
client (Palm) devices

4. Data is always up to date for all users since it's
being maintained in a central place.

If you want to go the 'decentralized' route and synch
data to the Palm, maybe also consider using SQL-based
databases running on the Palm; I only have theoretical
"experience" with Oracle 9i Lite, but it might make
life easier for you (simple to perform queries and
synchronize data).  I believe Sybase and IBM have
similar offerings.  Disclaimer: I work for Oracle.

Hope this helps,
Oliver
