Hi Colin,
Here is the most detailed instruction: http://poodll.com/documentation/1.0/1/poodll-2-for-moodle-2-x/
Trust me: it is very easy to installl/update Poodll for you Moodle, without any need of changes from you IT department, everything can be done through the 'Install plugin' interface. It is so easy to use as out-of-box and work well!
Trust Justin: Any plugins from Poodll, is USEFUL and reliable, never crush and always up-to-date.
I am happy to answer some question if I could.
All I can say now is: Install Poodll and try it, you will see the Poodll lovely buttons appear inside the tool bar of HTML editor; or as a big button in the submit assignment field; or a camera in the 'Add New Entry' form.....
