I agree.

  - Solution should work for both Wheezy and Sid
    (-2 in Sid currently has no celt support, and celt is the most widely
     used codec in mumble on the 'net)
  - Would use celt 0.7 as well as 0.11
  - Celt library can be removed, which a lot of effort has gone into
  - Larger diff in mumble
  - Would greatly irritate mumble maintainer

  - Smaller diff in mumble
  - Only uses celt 0.7
  - Proliferates library that upstream requested removal of
  - No DD found to maintain celt 0.7 library (yet)
  - Would somewhat irritate mumble maintainer
