  I am interested to see how you pass the InputStream.  In order to do
that, I had to apply the following changes to Calabash:

  PS: Maybe we begin to be far off topic here.  I don't feel
comfortable to post Calabash Java code here.  But there's nowhere else
to post that, sorry guys.  Maybe it's time to get a product-related
list?
