Engadget has an post on the Netgear WGT634U. It is a 802.11g Access Point that has an USB 2.0 port that will let you share a hard drive across a network. I am not sure what protocols it uses to share the hard drive, but I am assuming that has implemented samba. This would be a good solution for someone who needs an 802.11 access point, but also wants to share files around the network.
