     The latter ticket's discussion section is quite interesting.  After
reading through it, it seems to me that the problem in Roger's point C
would be best dealt with in vidalia without regard to IP address or
presumed country.  When asking whether the user wishes to run a relay,
vidalia's dialog could include an instruction something like this:

	"Before you decide to run a tor relay, please consider whether
	the government of the country where you live and/or would like
	to operate a relay might target you for any kind of abuse if
	that government noticed that you were running a tor relay."

As long as the people who have volunteered to provide translations for
vidalia's and/or tor's textual interactions with users have sufficient
skills to provide such a cautionary note in all of the most necessary
languages plus two or three languages spoken widely around the world,
then that should take care of the matter.  I share the concerns of both
Roger and Sebastian regarding undesirable potential results of automating
the rejection of entire countries of relays.
