this is where multi-path transports, which resist attacks against
traditional in-order or stream oriented transports - inherently
encumbered by serial datagram sequence. sadly, such transports also
require user space stacks and significant complexity. [see past
threads on multi-homed, multi-path SCTP w/ DTLS/IPsec telescopes, as
just one possible shape of could be...]

future ideas, plausible or no,
 Matryoshka does not solve even the known problems, let alone beat Tor
at the privacy game.


... fun subjects for exploratory development, perhaps when Tor Project
gets a research endowment. :P
