The important part is the configs, other than that is just another distro. a very small niche group serviced this distro, and it seems to be derelict. The useful part of BZ mesh is USB bootup. so any machine can become and unbecome a node. sometimes something is finished and nothing further is done then a new way pops up. the advantage to porteus is its pared down for rapid boot up, to reestablish a node while walking about on the fly.
