###An Action?
Yes, maybe this is at the moment not so much an ACTION but a project to figure out what works and condense it later into a clear step by step guide. But maybe a hypothesis for an order of steps can be created now and written down to be tested?
###Physical Space
Yes, from what I learned a permanent space is key for the community engagement.
So in an ACTION script this would be one of the steps - find a space. 
###First Module
Some people love more to talk and fantasize about things than doing them. An open question about what should be the first module is what would keep them active and together – for some time. Others really like to do things instead of talking about them. Knowing: No theory survives first contact with physical reality.
So it is good to focus on getting stuff done. Keep the discussion part as short as possible. It is important to pick a module that inspires and motivates you - and maybe one or two people more.
###Events
Events have pros and cons. They make it easier to mobilize a group of people and get stuff done. I think they work because they ask for short term commitment! And naturally the longterm fall out is usually very low.
But they do create opportunities though. When people wanted to found the Meta-Lab in Vienna they had a first meeting with almost 50 ppl attending. At the second meeting were less than 10. But those built the the Meta-Lab.
If people continue the collaboration depends heavily on soft factors - do they like each other, are they on the same page and comfortable around each other? An event can help to find each other.

The likability part becomes less important though once a physical reality is created – a working module in an available space for example. Shared resources people have an interest to have access to or even depend on change the soft factors or make them less important. We all use the streets in this city, we depend on them – they structure our live/have their own intentions – and we collaborate to maintain them (by paying taxes). It really does not matter anymore if you like the other people on the street. This is what is at the other end.
If you will the streets are a community member in this city.
An hands on event can help to create a physical reality - for example build a first module – create this community member.
I think I like that about OSCEdays - that it is - for me - about creating this physical community members, that are unpredictable then: No theory survives first contact with physical reality. But start to follow their own intentions.
The rest around it - the soft human factors - are too complex and unpredictable. So let’s try to get this new physical community members and see what they’ll do to us.
And if those community members are created in or with a culture of openness … if they breath openness … well, then they are community members of an open community. Let’s see how this comes together (and if).
‘Open Source Circular Design’ asks for physical community members that are unknown, and I’d like to meet. 
(Open Source = built for or to be picked up by a community)
###Physical Module
So that is probably why I think to have a simple step by step guide about setting up a first module is really interesting: Step 1: Find a physical space Step 2: Study the building plan … source materials … Step 3: find at least 3 ppl. willing to maintain the module for a while…. How can this list of steps be designed that it makes the emergence of the framework you are thinking about likely? To have the ‘theory’ of this framework in the back of your head is good - it is a good starting point and will help you to design the steps (and I really like that theory) - but don’t forget no theory …
Sorry for the long post. Just realized I have written down here some of the points that are core to me about OSCEdays I have never expressed like this before. So thanks for your questions. @BoST have a look at it.
