We used it back in the last century.. with Win98. I would call a friend that lived down the road. He'd set his computer to answer the next call on the software, then it would remote desktop. This was dial-up on 33.6 modems, before 56k. You could transfer files and all sorts of cool stuff. We would play 2 player games like chess, alternating turns and sharing the mouse pointer.

This was back when AOL charged by the hour, or shortly after. idk, never used aol except for the free floppy disks.
