Ah, I like this.

I'd also commend the Scuttlebutt approach to this (Scuttlebutt is a 
"curate's egg" of good and bad examples), which is to include the type of 
key in the canonical representation:

{
   "author": "@FCX/tsDLpubCPKKfIrw4gc+SQkHcaD17s7GI6i/ziWY=.ed25519",
   "content": {
     "type": "pub",
     "address": {
       "host": "one.butt.nz",
       "port": 8008,
       "key": "@VJM7w1W19ZsKmG2KnfaoKIM66BRoreEkzaVm/J//wl8=.ed25519"
     }
   },
   ...
}

The ".ed25519" making it clear what we're dealing with. Instinctively I 
like the multihash thing more, but the Scuttlebutt form has the merit of 
much better legibility/obviousness.
