Hey Lars,

I agree that the activity in here is rather low and it looks like not 
much is going on.
But I see that like Peter explained in his mail: Cocoon 2.x has matured 
so far that nothing really is missing;
Cocoon 3 has not received much attention (yet?), so there isn't a huge 
demand for changes or additions.

However that does not change anything about the seriousness of this 

Reinhard and I started working on Cocoon 3 because we wanted to have a 
Pipeline API and a very slim and lightweight Cocoon.
When we reached the feature set we needed for our project we stopped 
adding to it - there isn't much sense in adding stuff you don't even 
have a use case for.
Simone joined very quickly and added things he needed for his project(s) 
and then some people kicked in and had ideas and improvements.
I find that kind of growth very natural and healthy.

So I see the rather long release cycles and slowly growing feature list 
as a sign of less demand, not of less commitment and I'm absolutely 
confident that new (reasonable) ideas and requests will be met and 

Bug-fix and feature releases should be expected as with any other 
project (albeit with a slightly increased cycle)
I don't expect another rewrite in the foreseeable future.

Contract work on Cocoon 3 is definitely a possibility, assuming the 
usual conditions (time, budget, etc.) work out.
