[Phpgroupware-users] Laptop setup for offline access to phpgw data?

[Brian Johnson]

I'm running phpgroupware (on Postgres) at work and am looking for a way to have
offline (ie not connected to any network) access to my contacts on my laptop.  
Of
course, I want to be able to edit the data and have it sync back in when I
reconnect.

So I've got my dual boot laptop with Postgres 7.2.1 on the Linux side and the 
same
version running under cygwin on the Windows OS

I can't get the two to share data yet since the windows posgres under cygwin 
can't
see the Linux ext3 partition and the Linux postgres can't start up when I soft
link /var/lib/pgsql to the matching directory under the mounted windows 
partition.
I think it's because postgres runs as user postgres by default and everything 
under
the mounted windows partition is showing up as root.root ownership with u+rwx 
g+rx
o+rx permissions

Anyway, I start thinking, this whole exercise is so I can get access to the LAN
databases when the laptop is disconnected - so I start researching Postgres
replication projects - and come up a bit confused

This thing is starting to get very complicated.  Does anyone have a simple way 
to
set up a laptop to have offline access to database data (with the condition that
changes to the offline data must sync back into the main database when 
reconnected
to the LAN)?

I know that MS Access and the MS Briefcase app handle this very nicely, but my
contact database is based in PostgreSQL
