That would be me asking the question, as a reply to Don's concern regarding
the 'prorietary extension on a 24 mo. release delay'

I noted the use of the words "demo code" rather than "core code". That
bothered (and still bothers) me, but I didn't reply at the time,
since there was already enough heat in this thread. I'll take your
interpretation to mean it's just a matter of semantics.

Mixture of the silent schedule slip on the core code, and the explicit
statement on the page regarding the 'proprietary extensions'
with a delayed source release.

The biggest problem I see with having core developers making proprietary
extensions is the potentional for conflict of interest when and if
some of us donate equivalent code to the core. The core developers who
have also done proprietary  versions will have to be very cautious
when working on such code. They're in a bind, with two parts.  First,
they have obligations to their employer and their employer's partners
to not release the closed work early. Second, possibly ignoring such
independent extensions, or even actively excluding them for the core,
in favor of their own code. The core developers _do_ have a bit of a
track record favoring each others code over external code, as is natural:
we all trust work more from sources we know better, especially when that
source is ourselves. But this favoratism could work against the earliest
possible open solution.

I'm still anxious to see the core patches needed to support replication.
Since you've leaked that they work going back to v6.5, I have a feeling
the approach may not be the one I was hoping for.
