What is a Slug / an Asus?
A Slug is another name for a Linksys NSLU2; an Asus is – in the context of the Toppy – an Asus WL500gx or 500g deluxe. Both are small network devices; the NSLU2 is designed to allow you to plug USB drives into it, and makes them available on your network, while the Asus is a wireless access point with ethernet ports and USB connections. Both can have alternative firmware loaded on to them which effectively turns them into a small Linux system, connecting to your Toppy via the USB port, and making it available to other computers on the network, via a cable in the case of the NSLU2 or wirelessly for the Asus. Note that, in the case of the Asus, you must make sure you get the gx or deluxe version – other versions only have a USB1 port, which is much slower.
