Attorneys from my former client Torys, LLP have published an article on workplace policies for cameraphones.

It's an interesting piece, and I'd like to comment much further, especially on some of the issues that have been left out. But I feel proscribed; for two reasons: first and foremost, loyalty to a former client, but second, the fact that the mobile blogging tool Justin developed and launched about a year ago - Airblogging - has been used on occasion to post live photos from workplaces. The results are usually positive, both for the blogger and the employer, but of course they needn't necessarily be.
Accordingly, I will re-affirm the obvious point, just in case: policies should be aimed at users and usage, not at the underlying technologies - which can always be used for good or ill, depending on the intention and motivation of the user.
