Some bugs related to HTTP:
* when using authentication, the password is displayed (you must enter username/password, this is not very discrete...)
* when playing a VBR MP3 with ID3v2 tag via HTTP, the Xing VBR (meta-)frame is not correctly understood and then not used (seeks badly and false song lengths).
* authentication when loading a playlist via HTTP is not supported (I get a 401 Authrequired error, no prompt for password)
* if a playlist is loaded via HTTP, files without paths/URL in the playlist are defaulted to the current directory, but theorically should be defaulted to the server containing the playlist.
