------------------------+---------------------------------------------------
 Eventually we want to ship the standard Vidalia bundle with a set of
 supported client transports. We don't want to launch all of the possible
 transports when Tor starts, because most users won't ever configure a
 bridge line that asks for a given transport.

 So the client managed transports should launch only when we are configured
 to use a bridge that needs them.

 And maybe they could be closed after we no longer have any bridges that
 need them. That could certainly wait and be considered a "later feature"
 though.

 Do we foresee any client transports that would want to start earlier than
 when a bridge shows up that wants to use them? I guess that ties into
 #5010.

 Another option would be for Vidalia to paw through your bridge lines and
 know to setconf a given ClientTransportPlugin line when it sees a certain
 type of bridge line. Putting the smarts in Vidalia is probably a poor
 choice though.

 [I'm not sure which component this should be in -- either a Tor one or the
 pluggable transport one. Picking the one Nick is more likely to see, for
 now.]

 [I'm also not sure which milestone to use. We can push it back to 0.2.4 if
 it's too much like a feature. That would mean that our "normal clients
 using pluggable transports" bundles will want to use 0.2.4.]
