I just got my Sony FSV-PGX1 Portable File Server. It's an interesting device. It a little linux box that can run on batteries. It has nfs, samba, telnet, http and ftp. It has a 20G HD. There is a web interface or you can set it up with the little lcd display and arrow buttons on the box. If you get the cradle, there is an ethernet connector. The box has 802.11b built in. It's basically a file server. It can be set up as a DHCP access point, DHCP client or fixed IP address on both the ethernet and/or the wireless ports. It can be some sort of "bridge" although I haven't figured that out yet. Obviously many uses. Too bad it doesn't do rendezvous.
