[tor-dev] Rewriting tor-spec to be crypto agnostic

[Watson Ladd]

Dear all,
I'm busy rewriting tor-spec (well, mangling it) to be crypto agnostic
(read: shoving hard choices to later). In the process I am trying to
make it a bit clearer.
The spec seems to hold open the possibility that nodes not on the two
ends of a circuit can send recognized RELAY cells (the role of OPs in
processing
RELAY cells is also unclear). Is this the case, or is this not
supported given that there are no points at which the spec explicitly
calls for them to be sent?
Sincerely,
Watson Ladd
