Yeah, although we have to keep in mind that's a new API we're not even 
using yet for volume attach, so anything I'm thinking about here has to 
handle old-style attachments (old-style as in, you know, today). Plus we 
don't have a migration plan yet for the old style attachments to the new 
style. At the Pike PTG we said we'd work on that in Queens.

I definitely want to use new shiny things at some point, we just have to 
handle the old crufty things too.
