Should work.

We also have a seperate DNS network running with 6 powerdns and although the actual mysql database is local to each machine, it is infact the same database as all these 6 databases are replicated through a multi-master setup.

  I know, but if I have a mysql backend to the superslave instead of sqlite3,
  I can do deletes off the superslave backend database remotely.  The question
  is, is there any reason why I can't simply point all superslaves to the same
  mysql superslave db and have it work properly?
