Hmm, maybe I spoke too soon. I think this is a nice compromise:
https://github.com/Homebrew/homebrew/compare/master...afb:0install

It will allow you to install the latest and greatest from 0install
and from OPAM, or it will resource the modules at time of release:

484K	zero-install-2.8.tar.bz2
24K	zero-install--biniou-1.0.9.tar.gz
24K	zero-install--cppo-1.1.2.tar.gz
16K	zero-install--easy-format-1.0.2.tar.gz
72K	zero-install--extlib-1.6.1.tar.gz
808K	zero-install--lablgtk-2.18.3.tar.gz
304K	zero-install--lwt-2.4.6.tar.gz
108K	zero-install--ocurl-0.7.2.tar.gz
104K	zero-install--ounit-2.0.0.tar.gz
92K	zero-install--react-1.2.0.tar.gz
16K	zero-install--sha-1.9.tar.gz
52K	zero-install--xmlm-1.2.0.tar.gz
28K	zero-install--yojson-1.1.8.tar.gz
2.1M	total

In the end, it was just about telling opam which versions to use...
It will still try to download any missing parts, so that it works.

And now it is easy to update the modules, for 0install 2.9 and on.
Since they are all statically linked, no need to "vendor" anything.


This variant should be able to make it into the official brew repo ?
The linuxbrew install is reasonable, so the bottles should be small.

$ brew install 0install
Cellar/zero-install/2.8: 34 files, 11M, built in 107 seconds

--anders


PS. In the end I made do without any fancy opam scripts.
Just reset the opam-repository to the time of release...
