Comment (by teor):

 Our current plan is to use a path like this:
 C -> M -> ES

 Where:
 * C is the client running this code (call it dopiaza = two onions)
 * M is the relay we want to boost
 * ES is an Exit that only exits to its co-located HTTP Server with a
 single N MB file
 * N is 10*(the observed bandwidth we want the relay to have), we like 10
 MB P(1000 consensus weight) at the moment

 We can have a 15 second timeout, which allows 5 seconds for establishment,
 and 10 seconds for the relay to return some data.

 And we should probably only boost relays that are:
 * below 1000 consensus weight (they don't get much client usage),
 * below 1000 observed bandwidth (they don't see much bandwidth),
 * have an advertised bandwidth rate of 1000 or above (they want some
 bandwidth),
 * observing below half their advertised bandwidth rate (limit) (they want
 extra bandwidth).

 There are currently 619 relays that fit these criteria (~10% of the
 network).
