H5P standard
I've played around with the standard a bit (used the Drupal 6 module for testing) and am very impressed. You guys did an awesome job.
I have some questions/thoughts.
# Namespacing
Is there a particular reason to force packages to be namespaced with H5P ? It could be interesting to allow namespaces specific for "vendors" (or clients, if you will). This will reduce the chance of conflicts, as H5P will quickly get full.
