[tor-talk] A possible way to make end-users to contribute to Tor exit traffic

- it is *not* a good idea to run exits from your home (limited exit
policies are no guarantee for no troubles)

- most users will probably have asymmetric bandwidth (slow upload) and
contribute little bw and uptime, while every relay takes a certain
amount of bw to be distributed through the consensus to clients
(where is the break-even point?)

- most users are probably not fine with publishing a public record of
when they start and stop their torbrowsers (something that could be
deduced from seeing exits showing up on client IP ranges with certain
patterns)
(Makes certain correlation attacks easier where an observer sees your
exit showing up and correlates that with login times of pseudonym accounts?)

- only a small amount of users will opt-in to something potentially risky
