Hi,

When we were having a bit of a moan about skype earlier it made me think
of this: Information is leaked from an encrypted call when variable bit
rate codecs are used. It doesn't just apply to skype though.

The first link is quite easy to understand. The second two are pretty
tough going academic papers on the subject.

Cheers,
John
