+Tom Davidson was having some problems with port proxy.  I guess he just
+wants client-side -L and -D to work, which they do work, so far as I
+know.  But I tested, and -R does not work!  My phone seems to have some
+sort of firewall, it hangs instead of saying connection denied.  So maybe
+-R isn't bypassing the firewall.  Another possibility is that dropbear
+simply doesn't support -R, but I kind of thought it did?
