[Zope] ADO Database Connections

[Michel Pelletier]

There's a few issues in your email here that I'm going to have to punt
on George, because I can't speak for them.  But I will try and help with
a few of them.

I agree.

Python has a DBI standard like Perls.  From what I know about the
situation, it is not as mature in terms of supported platforms or
features.  Some people also have beefs with the Perlish way in which it
was done in Python, not leverging Python's OOness enough.

We commercially support an Oracle and Sybase Zope DA.  DB/2 should work
with the ODBC DA, I'd imagine?  I'm not certain.

We offer our standard commercial support for Oracle and Sybase.  The
information is on the digicool.com site.

There are pretty vaild concerns.

I'm not really certain, but it's not really my place to comment on that
either.  We've been moving along pretty well on our FastCGI support
against mod_fcgi.  I don't think anyone has approached FastEngines to
test the waters WRT Zope.  They're not a new startup, so I would imagine
they have support personnel for this, whether or not you want to be the
test case...

yes.

It's unexplored ground, but I definatly look toward it optimisticly.
