I really appreciate your help on this matter.

This is great; so I can setup a merge replication between clients and one SQL replication server, and then setup a transaction or snapshot replication between the SQL replication server and the customers Oracle / SQL server.

I will create a Publication for a Non-SQL Server Subscriber from the SQL Replication Server and the customers server will subscribe to this publication.

Thanks for the input.

Has anyone had any experience in trying anything like this out before?

Many thanks,

Laurence Proctor
