Dariusz, just to clear out another situation:

EULA for servers are different. There will be no need to buy 50CALs, the
first 5 will be suficient.
Once again, I'm just reporting what the lawyers told me.
That's why the price diference from a XP Pro to a Server Edition
(Starter, 5CALs included) will not make so much diference in a 50-users
software application.
