Ok, I see what you mean.
My initial concern was that I cannot use sitemap to alter the processing
flow of Cocoon dynamically at run-time. Well, I see that this is
actually not an issue. By combining sitemap, redirects and referrals, it
is possible to almost duplicate the functionality found in Turbine. It
is not an exact match, but it is enough for me at least.

Actually, how well is supported the "referral" feature: together with
the POST data the browser also sends the URL of the original page

yep, it is similar... and separated in a better way, IMO...

Probably not... but I think there will still be some space for Turbine
under the sun ;-) Although I hate to see so much effort and talent being
put into a project that is "inferior", instead of putting it into Cocoon
that is the future.

Yep, that helped a lot to make the vision about Cocoon2 in my head much
