[chef] Accessing Knife's return values within a script (without shelling out)

[Hedge Hog < >]

Hi,
Having got to run Knife commands from a script, without shelling out,
all that remains is to be able to have whichever Knife method return
the data from the show and list sub-commands.
This too does not seem to be trivial, does anyone have any pointers,
tips or tricks?
Redirecting Knife's puts output is not trivial, Knife uses STDOUT
throughout (tut, tut) rather than the recommended $stdout.
The knife run method has output as its last method rather than
returning the data :(

Appreciate any help.
