[Zope] zope da's

[George Runyan]

I have a few quick questions:

why does zope use specific DA's instead of a common bridge like JDBC? I was
apart of a web logic presentation a few weeks ago and alot of the developers
liked the fact that a) they rewrote the socket/rmi api (it multiplexes n
requests over a single socket), b) jdbc (of course!) exists and we could
'move this from platform to platform' and not break anything, c) scalability
and clustering methods (they use master/slave stubs) which seems to be much
more complex than ZEO- but it load balances at the service layer.  any
comments?  

but I am interested in the jdbc vs. custom built DA's
