Just sync your Palm to both of them. Unless the same appointment is
changed in two places, everything will just work. Conflicting changes
will result in both copies being kept, and you'll have to resolve it by
hand and sync again.

Thanks, Jim. So the scenario is

1) Laptop <-> Palm
2) Palm <-> PC
3) Palm <-> Laptop

or,

1) PC <-> Palm
2) Palm <-> Laptop
3) Palm <-> PC

What I was hoping for, and I should have been more
specific, was a way to synch between two computers
running the Palm desktop. That would take three steps
down to two steps

1) Laptop <-> PC
2) Laptop OR PC <-> Palm

But on further thinking, that scenario is flawed - one
last synch is still required, since any of the three
machines involved may have new data, whichever machine
synchs with the Palm in my step two may still have
updated data from the palm that the other computer
doesn't have. The third synch is still required.

It very much looks like three machines, regardless of
the platform will require three synch operations.

This seems like it boils down less to a software
solution than a simple exercise in logic - a fox and
geese problem, if you will:
2 machines require one synch operation -
3 machines require three synch operations -
4 machines ... five synch operations??? -
5 machines - my head hurts. seven synchs?
n machines - anyone here got a formula?

Cheers,

Conrad

Think it goes something like this:
1 machine needs no syncs
2 machines need 1 sync
3 machines need 3 syncs
4 machines need 6 syncs
5 machines need 10 syncs
6 machines need 15 syncs
So guess it is n machines need "n(n-1)/2" syncs
FWIW

Yes you are of course correct.
So the formula is then (2n-3) syncs for n devices.
