Just shipping the .pyc files has a few advantages:

* you can be sure that the customer hasn't modified the
  product and thus support requests are easier to
  handle

* the customer won't run into issues with the .pyc
  and .py files getting out of sync (e.g. due to
  permissions of the .py and .pyc files being
  different), making upgrades a lot easier for
  the customer

OTOH, if you want to help us make the product better, then we
should talk :-)
