[LEGAL] SuSE as back-end for proprietary software?!??

Hello! Could you please tell me if it's legal to give away SuSE 9.0 minimal auto-install CD copies (250MB or so...) - not to sell, but give away, actually, because we sell only our proprietary software. I want to sell my proprietary software but I need a back-end for my product - and, being a SuSE fan, I would like to promote SuSE, too - without interfering into the SuSE product, obviously - I intend to sell a complete separate and client-oriented product. Thank you Radu
