[Pan-devel] DataImpl abstraction

[Tom Tanner]

I've been playing with using a database backend rather than files and it 
seems to me that the DataImpl class doesn't really do what it's meant to 
do. Or at least it and the Data base class. For instance there is a 
Server object and an associated list type that exists in DataImpl. But 
that is very heavily tied in with the gui and a lot of other stuff.

I'm beginning to think that either the DataImpl class needs to be a base 
class for yet more classes or there needs to be a small abstract class 
which is passed to the DataImpl class which provides for reading data 
from/writing data to the desired storage system. I'd prefer the latter 
as it means it's much much easier to provide an upgrade path (or if not 
easier, at least cleaner).

However said small abstract class would require accesses to things like 
the Server class and the associated AssocVector<Quark, Server> container 
type. which would require breaking up the DataImpl class.

Which is all getting very messy and I'm just pinging the list for 
thoughts/suggestions
