Just a heads up, if you do decide to enable OpenSSL so you can do encrypted MySQL replication. There are two bugs that will affect replication and the mysqldump command. They're as follows:

Bug #24148 regression tests hang with SSL enabled
http://bugs.mysql.com/bug.php?id=24148
http://lists.mysql.com/commits/17286

Bug #27669 mysqldump: Got error: 2026: SSL connection error when trying to connect
http://bugs.mysql.com/bug.php?id=27669
http://lists.mysql.com/commits/24329

This may cause lots of problems with MySQL and SSL Replication using OpenSSL.

Cheers!

If you've ever required OpenSSL support enabled for MySQL Server 5.0 under debian, then you will need to recompile MySQL. Under Debian this is very easy.
