Remote feed lists in RSS Bandit
Joshua Allen mentioned you can export your feed list from RSS Bandit.. newer versions of RSS Bandit also support automatically posting your feed list to a remote server, and retrieving a feed list from a remote server.
It currently has three protocols that it can use to do this - file share (where you enter a UNC path, handy if you have multiple computers on a LAN and you want to share the feed list between them, or you have direct access to a web server where you want to post it), FTP, and using the dasBlog API.
(This is support I added to RSS Bandit some time before the last release, I never mentioned it here).
