got it worked out.....
Qtopia desktop 1.5.5 does sync..
put the Z on the network (wireless) as 10.0.0.5.....
in the pc-link use tcp/ip, put another host in there 10.0.0.14...
used the magic tool netcat
nc -d -L -p 4243 10.0.0.5 4244 -vv -n -d
(basically says, any connections to 4243 forward to 10.0.0.5 4244 (zaurus)
on the pc (10.0.0.1) put in to sync with 10.0.0.1
On the pc, I press Sync.... straight away I hit \"start sync\" on the zaurus... it loads up the syncing software to try to connect to another host.... but the pc connects and sync away...
its a funny hack... but it works!
