this looks like an interesting talk; i wish i could have seen it in
person. some comments...

is there any research / observations to support this claim? i'm
curious. (i think Tor will always be "slow" compared to direct
traffic. this is a feature, not a bug, and exists independent of any
particular transport protocols...)

i wish i could add a prerequisite before this item: "Implement
datagram based transport" :) commodity routers even now have problems
with NAPT table entries for busy Tor / other network apps. a UDP
transport would open up effective new NAT busting abilities and bypass
some of the windows / weak router NAT table conn tracking issues that
make scaling the existing TCP implementation difficult. i know the
DTLS proposal hasn't seen any attention lately. is this potentially
going to resume sometime, or is an entirely new proposal needed? (the
UDP section mentions more research / hacking, maybe even both? :)
