Sure, here's a few:
* Create a resource via something like Chef::ResourcePylabsQshell.new,
set the values you want and then use run_action to run it, similar to
this: 
http://github.com/opscode/chef/blob/master/chef/lib/chef/provider/remote_directory.rb#L99-108
* Use Chef::Provider#recipe_eval
http://github.com/opscode/chef/blob/master/chef/lib/chef/provider.rb#L61-77
* Make your qshell functionality a ruby Module that you could mix in
* Make your qshell functionality into an "implementation class" and do
the same thing as the previous suggestion, except with composition
instead of inheritance.
