Integration with CMF is still to come. It's the planned way where OF=20
(OpenFlow) will go but it still is going through its very first few steps=

Meanwhile some developers in Icube are maintaining the product version of=

OpenFlow that now got to version 0.7.

Julian Munoz Dominguez is also taking care of a cvs branch of CVS that=20
develops an OpenFlow version of OF starting from the old 0.4 architecture=

A graphical way to design processes for OpenFlow would be most welcome. P=
oint=20
is that we were oriented at having a web-based tool, so the graphical pro=
cess=20
design toolkit would have to be web-based as well (using Java, maybe).

Documentation is lacking right now: the main problem is that documentatio=
n is=20
not up to date with the current OF version. We hope to be able to give so=
me=20
documentation soon...

You might want to check out the http://www.zope.org/Members/vds OF=20
documentation anyway: it might give you a generale idea of the engine.

Thanks for your contribution,
