I will be breaking the original Brainstorm for this into manageable chunks per Quim's suggestion.

I have an idea how to accomodate his concerns and mine at the same time. Since the Brainstorm tool structure does not handle metastorms, I will use cross-referencing to connect the individual proposals. I also plan to create a master thread here to "rule them all and bind them". To that extent, I propose we create a new prefix called [Metastorm] to identify such threads. The first post of such a metastorm would list the individual Brainstorm proposals and provide links.

I think this is a good solution in lieu of a more functional tool.
