I initially proposed a Cocoon installer based upon AntInstaller, because
I was starting to use it for my own stuff. I then switched to NSIS,
which is more capable. However, here's some comments:

1. NSIS, while powerful, is a real step backwards in software
   development terms. It feels like C scripting, with replete with
   pre-processing instructions. Having said that, it _did_ produce
   a nice installer.
2. Any installer for Cocoon _must_ be able to handle dependencies
   between blocks. This is not a trivial task in _any_ installer
   package, I would suspect
3. As has been said, we cannot distribute a Sun JVM with Cocoon from an
   Apache server. However, we could potentially distribute it from
   somewhere else. But, for an installer to survive, its maintenance
   needs to be taken on by the whole community.
4. A pure java swing GUI for installing Cocoon, along with block
   dependency handling, was committed to our whiteboard
   That could be used.
5. In the end, Apache is a 'do-ocracy', he who does, decides. So, go
   make something happen!
