[xwiki-devs] Proposal to push wiki-nodes, the XWiki/Cassandra demonstration over to contrib.

Hi guys, It's been a while since this demo was created but I was looking at my github and it has not been touched so I would like to document it and put it in contrib where it's available. I have a question about technique, this demo builds on the standard version of xwiki-platform but requires a special version of xwiki-enterprise. Is it ok to have a long term branch in the xwiki-enterprise repository or should the entire repository be copied into contrib? WDYT? Caleb
