Sounds good... but can we separate this from the installation system?

e.g.:

- We have a package ('abiword')
- It depends on another package ('klik-union-fs')

Now, when I do:

$ 0launch http://.../abiword.xml

Abiword runs in a new namespace (provided by klik-union-fs). Just as
Python programs need a Python interpreter to run, Abiword needs the
Klik union system (though actually Abiword doesn't need it because
it's relocatable; it already works through normal Zero Install).

Again, that sounds useful, but possibly for other programs too (e.g.
programs installed using apt-get). Will you be supporting multiple
'profiles' per program? e.g.

$ klik-create-profile abifoo http://.../abiword.xml
$ klik-create-profile abibar http://.../abiword.xml
$ abifoo
$ abibar

(where changes made in abifoo don't affect abibar).
