It appears that with JonDo (similar to tor), it is possible to use tor
as the initial proxy used to connect to the jondo network. Is it
appropriate to call this "jondo over tor"?

This can also be done in Whonix: https://www.whonix.org/wiki/JonDonym

Is it be possible to do the opposite, "tor over jondo", where jondo is
used as the initial proxy into tor? Particularly, by entering the jondo
ip/port settings into this vidalia panel:

What would the implications of each be, and is this kind of thing just
strengthening a link that doesn't happen to be the weakest in the first
place?

Which setup would you trust more, and could this cause any potential
problems?
