Current as of Chef 11.8.2
Opscode bundle RubyInstaller DevKit with Chef as their embedded environment. RubyInstaller DevKit is a basically a packaging of MinGW/MSYS. It's intended for Chef internal use only and does not include everything we need (but it's close).

Knife-Solo dependencies:

Chef
A SSH server (communication)
rsync (to transfer cookbooks etc)

Please note this is highly dependent on what Opscode bundle with Chef. These won't be supported by Opscode and could completely break your chef-client installation. Updates to Chef will likely remove rsync and it will need to be reinstalled. Opscode might stop using DevKit entirely without warning and break this whole technique.
