I'm particularly impressed with the iTunes Plug-in as this is my first foray into C coding since 1992 and, after a remarkable number of buffer-overruns, it's actually doing what it should - i.e. not crash iTunes immediately.
Both can be found here:
And will make it into the Applications page shortly.
SnarlMail and SnarlTunes should be considered deprecated, however I'll leave them available from the site in case anyone prefers to use them. In the interests of open-ness, the iTunes Plug-in doesn't currently support displaying the album artwork so that might be a reason to continue using SnarlTunes for the moment.
As always, feedback very much welcomed.
