Who, exactly, is bankrolling BayStar Capital's $50 million investment in SCO (money that will be used, at least in part, to continue to wage war on Linux)? Not surprisingly, some are figuring that Microsoft must be involved, some how, some way. BayStar and SCO are denying vehemently that Microsoft paid into the latest $50 million pot. But the Redmond software giant has made investments through BayStar in the past. What's a conspiracy theorist to think?
