Hi Johannes -- First, there are several companies and several unaffiliated kernel developers contributing here, building on top of frontswap. I happen to be spearheading it, and my company is backing me up. (It might be more appropriate to note that much of the resistance comes from people of your company... but please let's keep our open-source developer hats on and have a technical discussion rather than one which pleases our respective corporate overlords.) Second, have you read http://lwn.net/Articles/454795/ ? If not, please do. If yes, please explain what you don't see as convincing or tangible or documented. All of this exists today as working publicly available code... it's not marketing material. Dan
