Comment (by arma):

 Hopefully useful thoughts:

 A) Is the only reason we need ed keys in the consensus for this hashring
 thing? That seems like a sad reason to put in all the overhead for every
 client for every hour forever.

 A2) And if that is the only use, we could put like 4 characters of the key
 in, as just a hashring hint?

 B) Is there a longer term plan for phasing out rsa keys entirely, and
 replacing them with ed keys? If not, maybe prop224 hashring should use rsa
 keys.

 C) Maybe the consensus overhead isn't so bad because of consensus diffs.
 Or maybe it is? Has anybody done any follow-up on the consensus diff
 deployment to see what effect it has had?
