For purposes of Copyleft discussions, I think the appropriate metaphor
"You can enter my home if I can enter your home." But again, this has
nothing to do with the Artistic license (though your hypothetical
license to an artistic house does ;-) ).

My own view is that this case, if allowed to stand, would pose a serious
threat to more permissive, non-copyleft software licenses. Copyleft
licenses tend to be more obviously an exchange, and tend to have more
contract safeties built in.
But if a permissive license always includes a waiver to sue for
copyright infringement, and if the only recourse would be under
breach-of-contract, then this would seem to me to be very problematic
for BSDL authors, for example, if their copyright notices were removed.

To what extent is the Artistic License, the BSDL, etc. revocable at
will? I, for one, hope they are not. :-)

IANAL, but land-use law gets interesting in these areas, doesn't it?
Another tactic I have seen is, "you may use this land, provided that you
maintain it, and pay me $0.50/year in rent plus the $100 up front I
spent on legal fees getting this figured out." The rent in this case is
merely symbolic to avoid such issues (but again, this sort of thing is
always important; consult a lawyer).
