OK, I've basically done this and checked it in.
ArkHost.run() *is* simpler -- even if none of you will
believe it :-) -- so I think it's to the good.
We're down to three cases:

* host/user/group all OK -- just run the code in the
interpreter required; e.g. fire up '/usr/local/bin/perl' and
shove the code into it.

* user/group OK -- ssh <remote> <interpreter> and shove the
code into it.

* otherwise: start either 'sudo python' or 'ssh <remote>
sudo python' and do as Jonathan suggested.

Now, *perhaps* we should get rid of the first two cases and
run python for them, too -- we might then be able to *lose*
most-or-all of the code in preamble{Sh,Py,Perl,...}.
I.e. put the preamble-y things in the Jonathan pyscript.
