I think this is looking pretty good for the demo. Thoughts, @benkahle and @EvanSimpson?
Here's some output:

>I set you up a list of lawless resolutes, For food and diet, to some confession Of his true nature; and we ourselves compell'd, Even to the sweet: farewell.

>I thought thy bride bed to have his day.

>I the matter will re word; which madness Would gambol from.

>O, horrible most horrible If thou canst mutine in a dozen passes between your and him, he drowns not himself; argal, he that builds stronger than a foul and most unnatural murder.
Should we add some command line args for things like this to show more interactivity?
