The SD protocols aren't open standards. Ricoh can't legally include information about the protocols in their documentation. Without working implementation of the SDA's standards, FreeBSD is stuck. I don't blame the funding behind FreeBSD development for not ponying up the dosh; I think such fees are extortion made legal by intellectual property laws. But hey, it's the business. It's not like we're trying to make a good, free product everyone can use, right? _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
