I suppose this is true, according to the spec.  (When I tested this
out, the implementation seemed to match my proposal below rather than
the spec.  I haven't had a chance to look at it.)

However, it would be easy to change Tor slightly.  If Tor used four
ORs rather than three with .exit addresses, then there would be no
problem.  The only difference between using "http://myserver.exit";
rather than "https://myserver.com"; would be that the last hop would
use the Tor protocol rather than HTTP.

The situation for <img src="http://myserver.exit";> would be no worse
than for <img src="http://myserver.com";>

Cheers,
