Comment(by infinity0):
So using my notation, the super_1/super_2 architecture becomes:
:SOCKS(U)|tor-c|A=SOCKS(U): ->
:A=SOCKS(U)|obfs-c|B=obfs(U): ->
:B=OU|super|C=SOCKS(OU): -> # where OU == obfs(U)
:C=SOCKS(OU)|flash-c|D=flash(OU): ->
## internet
:D=flash(OU)|super_1|E=flash(D+OU): ->
:E=flash(D+OU)|flash-s|P=SOCKS(D+OU),Q=control(E): ->
:P=SOCKS(D+OU),Q=control(E)|super_2|R=D+OU ->
:R=D+obfs(U)|modified obfs-s|S=SOCKS(U),T=control(D): -> # typo corrected
from previous post
:S=SOCKS(U),T=control(R)|tor-s|Tor(U):
The nice thing about this is that we have a proof (I think :p) that
|obfs-s| does need to be modified for the obfs-flash-proxy combo (at least
if we go down this layering route of trying to re-use |obfs-s| and
|flash-s|), since there is no other way of passing D through to the
underlying |tor-s|.
