Yes, and discarded it for these reasons:

- fusefs is much more popular / has more file systems developed for it 
(and refuse is not 1:1 identical enough to be stable)

- it has a better concurrency model, allowing for potentially better 
performance

- it is older / more mature

There was a relatively recent Summer of Code effort to port puffs to 
FreeBSD, but it is in the same state fusefs was when it was being worked 
on: there are rough edges that need patching.

Of course, all this does not preclude anyone importing puffs in the future.
