Goals:
  - Heterogeneous (Mac OS X, Linux server, Linux workstation)

Solution:
  - include $operatingsystem. Examples:
    - http://paste.pocoo.org/show/181132/
    - http://paste.pocoo.org/show/181133/
  - Existing but patched package providers: appdmg, darwinport
  - My own package providers: appzip, pkgzip
  - Using /var/db
  - Configurable versions. Example: http://paste.pocoo.org/show/181134/

Deployment:
  - git push

Challenges:
  - I don't like the version numbers in package name (problem for requires)
  - Different package formats
  - Macports provider is very slow (package list)
  - Languages / I18N (error messages)
  - Software that needs CDs => mirror to a server
  - Original downloads get removed => mirror to own server
  - How to handle installation-specific data (localdata)
