I'm watching this closely, because the route you take will determine how fast you get hard-forked to irrelevance. This ought to be illuminating. Also, nice one about not wanting to "inconvenience" your disastercoin users, (to the detriment of everyone else) because hey, you're already hooking in to the Bitcoin hashing power, why limit your blockchain resource usage?
Just speaks volumes to what the priorities are here.

How will the update frequency cause a hard fork?
Or is it that you missed the Mastercoin train and you a slinging mud around because you can't now participate?
