Thank you for remind us of this E-Mail because it is an important and 
useful feature now that the Addons are much more easily to create and share.

I would go for the first two. We could use your install.sh script from 
the OpenNebula sources as a starting point. As for documentation I think 
it is a must have either way.

I think packages would be a barrier for contributing because not all of 
us know how to package for various system distributions.

This sounds great and would ease up the process of creating new addons. 
I am curios how would you deal with multiple 'types' of addons, like 
storage drivers, vmm, etc.

One step at a time, first the install and then the other two awesome 
features :).

Please tell me if and how could I help.
