5 developers is not a lot
Actually I think it is quite a lot, at least if you're using it as a yardstick to judge whether the company can trivially afford to pay for VS licences. Software's a profitable industry and if you've got 5+ developers and still can't afford to pay for licenses then you're doing it wrong.

This isn't aimed at small development shops. It's aimed at one man bands and start ups for whom licensing costs would otherwise be an obstacle.
