Also not *entirely* true: nothing prevents you from using the two masters

Your reads can go to both servers with no problems.
For reads that need to read data that was just written though, you
need to read from the 'active' master, as you can not rely on
replication to be instantaneous.

ssl is not enough for pci dss compliance. If you store credit card
information and are not pci compliant you can be heavily fined and have your
ability to process/accept credit card payments permanently removed.

You need to check pci compliance rules before you go replicating and
transmitting credit card data.

also consider that it is much more likely that remote slaves will start
falling behind particularly if you throw encryption into the equation.

Well, not logically valid in the general sense (in that naive
master-master replication can be self-destructive) but can be extremely
useful when utilized knowing all the limitations and potential pitfalls.

should not be used." Consider a table with an AUTO_INCREMENT id
