Can anyone update us on the status of mini magnetosphere plasma
propulsion (M2P2)?

As far as I know, it remains a paper concept with some major unknowns.
I don't believe anyone has yet funded an in-space test.

impulse, radiation protection, etc. -- but perhaps there is a hitch.

High effective specific impulse, yes. Radiation protection, no -- the
mini-magnetospheres are not big enough or strong enough to fend off
serious particle radiation.
