JoltID is the company set up by the founders that has the Skype P2P IP in it, that eBay failed to buy and thus
scuppered their attempts to sell Skype easily. One assumes Microsoft bought the IP but I cannot see it in print anywhere (and having seen "Deal Fever" at first hand I can easily believe they didn't....).
Anyway, if they did buy it then my view is that Microsoft overpaid, but it's a rational strategic move so good luck - they will need it, the devil to creating value now is in the execution into the SOHO/SME business market - and execution on acquired companies is
not a Microsoft strong suit.
If they didn't, then my view is that they are complete dingbats.....
