My estimation is that skype makes enough money to be a fairly profitable company with it's business model (<$1b per year revenue, small or negative profits most years) if that is the goal but, it probably doesn't merit $7b. MS will need to get more value out of skype than current skype out call revenues. They're probably planning something else.
