These new pads remind us of one of Campagnolo's offerings from the not-too-distant past: the "synt" brake pad. Those pads, made of a top-secret formula that at least looked like cork, didn't stay in the company's lineup too long. You can occasionally find a pair at the bottom of a parts bin. More on Synt is here.
As for Zipp's new pads, if they're like the company's other pads, they'll be available in a shape to fit Campagnolo's brakes. Zipp's web site: www.zipp.com
