NFC is not particularly performance dependant so having a lot of the stack in a daemon isn't really going to hurt anything too much on a client embedded device/phone. The bigger question is probably what it needs to look like the other end - ie the server side embedded devices doing transactions. -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
