Right. Someone digs up a two-post conversation from the altcoin observer thread and then the next day there's a post in the Stealthcoin thread saying they're going to implement it. Words are cheap.
Also, they're full of you-know-what when it comes to scalability. As smooth already pointed out in the AO thread, and I think correctly, the real benefit of a sqrt(N)-scaling ring signature scheme is stronger anonymity through larger mixins.
As it stands, the Cryptonote family doesn't scale to visa sizes even with mixin=2 (for which there's no benefit from the cited ideas), and neither does Bitcoin.

(edit: In addition to wishing more coins would copy Gatra's soft-start approach to block rewards used in Riecoin, more coins should copy Zoidberg's 1% ongoing dev fee from BBR. The incentive difference between a 1% premine and 1% ongoing revenue is HUGE. The premine invites a fast pump and dump; the 1% ongoing revenue motivates continued long-term development.
Heck - XMR should add this so the team has food on their plates. :-)
