Rule based Database Replication Tools

Hi

Can someone please show some pointers for using any rule based software/tool for Database/file Replication between Corporate and 1200+ Store nodes?

Some of the tables are bidirectional and some are unidirectional (either of the way).

These nuances should be configured by a rule base/rule engine.

Database is in SQL Server 2008 across all nodes and central server.

Thanks, Jebah
