Well, I may be wrong but wouldn't XSLT be ideal for this? If Hijack squirted out the XML data for the playlists and transformed it using a user designed XSLT template then dished out the resulting HTML to the user's browser this would do wouldn't it? I know that this relies on the user being proficient in XSLT but maybe we could write an application which creates the XSLT file automatically from some user specified settings. Just an idea. What do you think?
