Non-emulated shmups that have online co-op?

[Jotamide]

I was wondering the other day the number of shmups that feature online co-op from last gen. The only ones that came to mind were Ikaruga, Radiant Silvergun, Deathsmiles I & II, Strania, Aegis Wing, Guwange, and Gundeadligne (Steam). But is that really it?

Nemesis Online is a prototype that is being (extremely slowly) developed on, but has some great levels worthy of being in real gradius games.

Mirror war is a Korean (if i remember correctly) shmup MMO. Good luck registering though, Korean games hate outsiders.

Also chicken invaders 3, 4 and 5. Don't play this unless you just want a laugh.

R-Type Dimensions has online co-op. I wouldn't suggest playing that way... unless 15+ frames of input delay for whoever isn't the host sounds like a winner to you.
