Yeah, I mean, it's not like there are any Flash download tools now or anything.

Or even digging through various directories to find where your video's been downloaded to.

For a while there, Flash was insisting on deleting its files (the directory entry is removed but the handle and content remain) in Linux. You can still find the filehandle through /proc and restore it.

Content control doesn't work so long as users own their systems and you've got to distribute it in some means or another.
