There seems to be some confusion -- this isn't a product to secure apache, it's a product to secure your web applications running on top of apache. It's designed to detect and prevent attacks on your app, not on the apache server itself.
It will suck on Roku, too, if you have a crappy/inconsistent connection. If it ever drops below a certain threshold, it will just degrade the quality to the next lowest stream it thinks it can support. Roku is worse than xbox/ps3 in that it seems to remember the resolution you usually stream at so even when the connection gets better (other times of the day, for example), it takes it a while to realize it and start getting the higher quality streams.
