How to set up ZEVO / ZFS on an internal disk while maintaining full disk encryption?

Short answer … two Core Storage logical volumes, both encrypted:

  • one LV, HFS Plus
  • the other LV, give to ZEVO.

You'll need ZEVO Community Edition 1.1.1 (1.1 is outdated).

In the answer to the linked question there's a note about Mountain Lion; OS X 10.8.5 makes things a little more difficult.
