11spd is a wider freehub driver than 8/9/10. Shimano has had theirs out since last year. It will work for SRAM as well. In general it is the same spacing as the Campy 11 setup but it is all a higher dish and the tension balance isn't as good as it was...not that it was ever great.
Everyone's 11 spd hubs are in the same boat. Been building with them all. Most hub suppliers are turning off their 10 spd units in fact. Mainly because you just use a spacer and can run a 10spd cassette on the same freehub body.
As a wheelbuilder who has been building 11 spd wheels for quite a while now....I can tell you that in my opinion the extra cog is not worth the loss in tension on the NDS.
Zipp is owned by SRAM BTW.
