[consulting] Copy Protection/DRM approach

[Sami Khan]

Lyrics sites are a good example. In some cases they retrieve content
using nothing by javascript (ajax) and then have a bunch of other
javascript functions to protect the content. So if you disable
javascript, you can't even get at the content.

So in theory you could do that, make the content show up through
javascript, would really even have to use ajax if you didn't want to,
just put the html as an encoded json string on the page and then load it
using jQuery, but it's a really messy way to do things and really just
ugly. However, I don't know of any clean ways of achieving that goal.
