I used to work for a messaging service provider and they had two 
systems. The first system was the service provider offering its 
messaging platform for its own domains and a hundred or so domains for 
quite a lot of clients and these were managed with BIND by hand.

The other system was used for solely one client and that client is a 
rather big Registrar, whom I shall not name, with thousands of domains 
of which a good portion (over 50k) were hosted by this messaging service 
provider since the registrar did not have its own messaging platform. 
All these domains were automatically managed with tinydns.

So I do not know how you 'outgrew' tinydns. After all the only part that 
involves tinydns is 'generate the cdb file from a database for tinydns 
to chew' or in other words, generating the cdb file for tinydns is the 
least of your problems to tackle.

The secondaries are handled just the same (actually, you do not need 
'secondaries' anymore...if IIRC, you just have to rsync the cdb file 
over so there is no real master/slave thing here)
