Great, thanks. I've made some minor updates to our page with your
suggestions too.

Sounds a bit like Joachim's 'relocation' table proposed a couple of years ago:

http://thread.gmane.org/gmane.comp.file-systems.zero-install.devel/882/focus=882

I never got around to implementing it, though. One problem for us (but
not for you ;-) is that people often install Zero Install non-root
(e.g. in their university account), and there we can't predict the
location of the cache directory because it's under $HOME.

(Klik has yet another approach to this, which involves cd'ing to the
directory first and using relative paths everywhere... of course that
causes a number of other problems elsewhere)

That's good to know. Can a package in one channel depend on a package
in another?
