I agree with raising the blocksize, but not by such a large increment.  If BIP101 was simply altered to curtail the increases it would be much more likely to gain support.  Chances are, most people are going to get behind a 2-4-8 increase, which seems far more prudent than 8-16-32.  Personally, I'd still like to see dynamic, smaller adjustments on a more frequent basis, like every week or two if required, but the idea doesn't seem to be gaining much momentum.  If I could code, I'd start an altcoin to test this idea out.  Would love to see it in action (with or without the voting part).  I guess it's more complicated that way, so less appealing as a result.  People seem to like whole numbers and simple concepts, so we'll probably end up with static limits.  Such strict rigidity worries me a little, but being stable and predictable is important too.
