No it does not.  You can have what ever you want: and it will work with
brilliance.

The Master writer can be on server1 the master reader server 2 then do
your replication.  You just have to take account for this in the design
of you code connection and query wise.  Ohh a heads up most python
database modules can support this way of connecting.   IE They are not
connect aware to more than one connection.  Meaning you can mix inserts
and selects from the write db and then from the read db at once. 

Nates comment in the latter mail is correct also in doing it.  I do this
all the time.  Just not with your truly (mysql)
