We were working to make it work, with partial success as you see later on.

Thanks, this is a nice video, although I find it a bit small and I get no 
sound with it on my machine.

I can't really say anything without seeing and testing the code though, 
where is it?

Also I have the repetitive feeling that we are suffering from 
communication problems. I think it would be essential at this point that 
Nicola comes to the mailing list himself (to this one or to plone-devel 
alike) and tell us about his code and experiences.



Also the lack of communication is partly my mistake, so to correct this, 
I take the opportunity to spread some information around about the 
history of the kss dnd story so far:

- First Godefroid and many others made a prototype dnd plugin that was 
based on scriptaculous and it worked in kss.demo.

- Later I and Alec Mitchell made an enhanced version of the plugin that 
fulfilled our real life use cases, it worked on Plone 2.5 and is still 
running in production. It was not clean and not really public although 
the code is in codespeak. Alec showed it in his presentation about 
relations on the conference.

The biggest experience of this (apart to see how extremely easy to use 
dnd from kss) is that the prototype library of dnd is not suitable to 
general purpose use from Plone, mainly because it only supported a single 
pool of dnd. (singleton class) And this is not sutable for generic 
application use.

- On the sprint we targeted to port the existing plugin to Plone 3.0 and 
jQuery. We failed to finish this. Still I made the existing plugin work 
on Plone3, and I almost presented it on the second sprint day, (but the 
projector broke and in the end I just told about it).

So the kss.plugins.sdnd does work, although it is for sure has problems. 
It is in the "kissbooth" project in Launchpad, and untouched since. Still 
it is not much use, since as I said it is unusable in Plone in its 
current state for anything else then prototyping. It does show though how 
you use the kss rule and parameters, and it does have two demos.
