Hi Ty,

To do this directly is planned for 5.1, i.e. multi-source replication.

Two ideas for pre-5.1 versions of MySQL that I can think of are:

1. To replicate from front-line server F(i) to front-line F(i+1)
server ending with the corp machine C, i.e. F1 -> F2 -> F3 -> C.

2. Let C replicate from each front server in an interleaved fashion,
i.e. first from F1, then stop, then F2, then stop, etc. You need
to write some script for this.

Best wishes,
Lars
