Since so many of these issues can only be answered by the implementors themselves, and since they each may well choose different solutions, it is very important that the different implementors keep in contact with one another, and are each aware of how the others are tackling the same problems.
There probably needs to be some kind of implementors' forum, perhaps in the form of workshops, or some kind of co-ordinating comittee in order to ensure that, at the end of the day, the different Clump implementations are able to interoperate successfully with one another.
