I can see other problems. TESS server (with their substitutes) has
to be fundamentally a trusted agent. Question is whether user
can always trust him. If TESS server denies the proper receiver
the decryption aid for an incorrect reason (say, a third person
has bribed an employee running the server or the like) what can one
do? Can or do most users like have such a trusted agent? Also the
communication with the server provides possiblity of traffic
analysis. That may not be beneficial.
