project alive or dead?
Project, I don't know.
PalmDetroit was Last Active: March 06, 2016, 09:29:54 PM
Which is good news , because his last check in before that was in Dec 2015, so at least we know he is alive.
So currently no active dev, but the PHS coin network itself is alive.
Check here 9 active connections.

Dormant does not means dead, just inactive until something changes to make it active again.
That being said it has enough users to keep the coin network running and it has an exchange with trading pairs for BTC, LTC, & Doge.
