Comment(by arma):

 The technical plan in a nutshell will be "first we get bridges working in
 an ad hoc way on ipv6, then we get bridge address lines and descriptors
 able to do ipv6, then we let clients ask for ipv6 destinations, which
 includes changes to exit policies, then we take a step back."

 We'll probably also want to point out the increasing value of ipv6 support
 especially for censored countries.

 Sebastian reminds us that we also need to consider the metrics piece of
 the question, such as "what is the impact on path diversity of having only
 x% of the relays supporting ipv6?" Along with that question we'll need a
 design for a "no relays support ipv6 until a switch gets flipped in the
 consensus" approach so we don't deploy an anonymity-risking bottleneck at
 the beginning.
