Sure, have a similar customer. They are right now using a set of
Perl-scripts which ship the logfiles to the slave, take care of the
status, apply the logfiles, validate checksums ect ect. The whole thing
works very well in combination with RedHat cluster software, but it
took several weeks to implement the current solution.
Not everyone wants to spend the time and the manpower to implement a
"simple" replication.
