Stefan,

I think Raphaël wants to know if a user can use any server in the circle 
to update or insert records and that the changes will be replicated to 
all other servers.

In another thread he stated that it was for maintaining student 
information on various remote locations (a student can login into the 
system on any of the locations).

What happens if a record is updated on two servers and the changes are 
forwarded to the other servers in the circle? I dont' think that this 
would occur often with student information, but both the student and the 
administration department might update a record "simultaniously" (in 
comparison to the speed of replication with several remote locations).
