Syncing one Palm to 2 Desktops

[Rob Horton <robh dongle org uk>]

Hi,

I'm trying sync one Palm (a Treo 600) to two different desktops
(one at home, one at work). In both cases I'm trying to get the
Contacts, Calendar and todo list synchronised into Evolution, so
I should end up with all three holding the same information.

I've got the home one working properly but when I try at work only
the Contacts get synchronised. Interestingly the Calendar and 
todo list appear in the log on the Palm but nothing seems to get
copied across.

Should this arrangement work in principle?

Do I need to do anything special with the Username / ID? I've
tried using the same as at home and a different one but it doesn't
seem to make any difference...

Thanks,
Rob
