In theory you can, but why would you want to pay so much for something and NOT have your own????? This is mainly used for corporate environment purchasing 100s of software licenses for 2000, XP, etc.
No, it costs the same too. Unless you are a corporate customer buying a certain number of liceneses. Or a reseller..... lol Hopefully you get the point.... lol

To answer the original question.....You should purchase your own copy. The last thing that you want are headaches.
