Okay, can the kernel cope with a device hanging off a USB port or integrated into the motherboard or a PCI card which provides wireless LAN capabilities with mutliple protocols running on it? Asynchronous data is 802.11 style, isochronous data is DECT sytle for SWAP, can't remember the protocols for Bluetooth. They will support a number of concurrent voice calls between handsets/apps software on your PC along with LAN activity (i.e. wireless printing from your laptop). In some instances the FreeBSD box will have to be a some form of controller which manages the routing of the network. [tutorial snipped].
