Techdirt sez that Skype has a deal with EMI to sell VOIP ringtones.
Perhaps they’ll follow the iTunes model and use the tracks as a loss leader to try and attract people to Skype — but that would be even more questionable, since it doesn’t seem like Skype does a great job of turning downloaders into paying customers.
I have a sneaky suspicion that Skype is about to get a lot better at turning downloaders into hard cold cash, downloadable ringtones notwithstanding.
