Bule says tuCloud and other companies like it get calls from Microsoft two or three times a year to audit compliance with licensing rules. While no one seems to know for sure how OnLive's licensing arrangement with Microsoft works, Bule says he is suspicious of the connection between the companies because its CEO and founder is Steve Perlman, a former Microsoft division president. Perlman sold a previous company, WebTV Networks, to Microsoft, and founded a company, Moxi, that later merged with Digeo, a company founded by Microsoft co-founder Paul Allen.
