Thanks, I've been trying Dropbox, and although I'm not very happy with it--for instance, I can't get it to create links for folders--it does create a file link in just the right format, and when I use the link in my browser, it launches the plug-in for MIDI files. So now I have to check on the blogging end.

I'll also report back on what I find out about SugarSync and SpiderOak (which I've begun using for security reasons), and maybe Google Drive. But since Google's Big Brother service unification and profiling changes, I'm not greatly inclined to give them my data nor let them track my browsing habits when logged in, much less allow them a direct window into my computer's file system.
