I'm also making changes to MimeTools. I've split the mime tag into two tags,
mime and boundary. This allows for the conditional inclusion of sub parts. I
am currently trying to allow variablized parameters to the tags (and not
having much luck!). I want to be able to say 
<dtml-boundary name="upload_file.filename()">
Anyone have any ideas?
