Getting SharpReader to save to a URL

Luke today noticed that you can open an OPML file from an URL in SharpReader. While this is great, what would be even better is if we could have the OPML file placed on a web server and Sharpreader would read and write to it (via FTP, WebDAV, a web service or what ever). I’m using SharpReader on several computers and it’s sure no fun trying to keep my subscription lists in sync.

Please? :-)
