I think that I may actually have a handle on this iSCSI thing. I have successfully configured an iSCSI target (the server that provides the disk space) on Linux (Slackware 12) and iSCSI initiators (the clients that use the disk space) on Windows XP and Linux (Slack 12, again).

This is all due to the "...impending storage explosion at work." Next up will be doing some test runs in a near-production environment in the office. This could be the answer to a lot of our troubles.
