&gt; You just need git and some sort of communication tool to distribute patches, email being the most powerful, flexible, and ubiquitous I&#x27;ve seen.<p>I would say that having a private NNTP server (one requiring an account to post) would also work in lieu of email.  In fact, it would be better than email because it would allow new members to easily browse list archives.  At least gmane already does something like that for some mailing lists.
