ofcourse, with a little bit of gymnastics, you can already do this today :)

what would be good to see described, and maybe something for Brian, is
to get the workflow documented for something like this. How I am seeing
this now is that its a case of a custom ks used at deploy time, which in
turn is from a different call ( eg. not a /node/get ), and comes with a
latency question ( ~ 5 min to 10 min ). What needs working out is how
the session management is then done.

maybe something like this :
- session is allocated at the time a call is made ( with no hosts attached )
- machine(s0 are provisioned
- session is populated at the duffy end, with the client ( user /
cico_client etc ) needing to poll for details, say every 60 seconds.

does that sound about right ?
