@deed02392: Yep, it's (finally) been tested, and should work pretty well since v0.43.N with USE_VOLUMD enabled. The big fat warning will be gone from the doc in the next release, and more hints dropped that K4 users should *really* enable USE_VOLUMD
.
And, nope, the readme's not outdated on the shared keys front, but I'm not shipping any public keys by default, for obvious reasons (and because it'd be useless anyway ^^).
