Merge Replication Weird Scenario

My topology:
On the national Server: SQL 2005 Enterprise
On the mobile clients: SQL 2005 Workgroup.
The Scenario:
2 mobile subscriber S1 and S2 to the same simple merge publication P1 on
server N
Day 1,
S1 and S2 both synch up with N and both go off to do fieldwork
Day3,
S1 and S2 both synch up with N.
S1 goes back to work
S2 shutdown the laptop and goes on 2-week vacation.
2 Weeks late
S1 Synch up wit the server and goes off to do fieldwork.
S2 meets S1 in the field. They workfield is in the North Pole.
S2 has the laptop with data 2-weeks old but no longer can have access to the
master publisher N to synch the replica and get latest changes.
S2 will have to sync with S1 since S1 database is fresh. The challenge is to
have S2 and S1 replica identical
The Questions:
Is it possible for S2 to sync with S1 and if yes then and how to go about
it… we need S1 and S2 to have identical replica on their machines?
Now that S1 and S2 are have identical databases and are both doing their
fieldwork in the northpole. Can they both sync back with the national
publisher N when they have access?
Keep in mind that S2 got its data updated from the replica on S1?
Thank you!
No, what you are describing is multi master replication and SQL Server does
not support it.
