[development] Multiple user aliases - Multiple user node, ownership

I have done the same in the ejournal module, but what is not possible
with this approach is to track ownership or assign rights to
individual users (as opposed to groups). Think of it in this way:
access rights may be rebuild by other modules, if you do not keep
track of  node-authors relationships, you are not able to recreate the
rights using information from node_access table only (using drupal
hooks) because access rights are deleted before being refreshed.
The proposed approach of node_uid table would solve this and many
other related problems.

I am struggling with the multiple authorship issue since the very
beginning, ie. D4.6, there are potentially a lot of modules who would
benefit from this functionality. I am sorry, that it is probably too
late for D6.
