A pretty clever attack. I wonder what the Skype people will do about it. (It seems like any algorithm that has e.g. a variable transmission rate will be relatively easy to attack.)

Not really, just make the variability of bandwidth not depend on the amount of data that's being transmitted... i.e., add a stochastic factor to it (random). If there's enough noise, you probably shouldn't be able to decipher the words spoken.
It's called traffic analysis
