That was then. This is now.
On July 3, according to Paul Cormier, Red Hats executive vice president of engineering, said Red Hat wants to work with the Microsoft to improve Linux/Windows interoperability.
"I want to talk to the folks at Microsoft about our two operating systems and how we can work together to solve real customer problems without attaching any unrelated strings, such as intellectual property," Cormier told Peter Galli of eWEEK.
Patent agreements, however, wont be on the table, as far as Red Hat is concerned.
Microsoft officials, though, dont see it that way. They say that the issues of interoperability and IP (intellectual property) are not completely separate, and have to be considered together.
Bob Muglia, Microsofts senior vice president for server and tools, said, "In terms of helping to drive conversations with those guys [Red Hat], were open to talking to them about interoperability, were always open to talking about this."
"But," Muglia continued, "It is necessary to have a conversation about intellectual property when it comes to open source, and you cant just sit back and talk about interoperability for interoperabilitys sake without fully solving the customer issue.
"Unless you actually address the issues around IP you havent fully solved the customers interoperability problem."
