I noticed this hasn't gotten much attention over the course of the day. Fridays are typically a little light on traffic, and the topic you're asking about is pretty specialized.
If you haven't gotten a response here in a day or so, you might have better luck getting your question in front of someone who knows by directing it to the Inline mailing list. See http://lists.perl.org/list/inline.html for archives and subscription information. It's very low traffic (sometimes months go by with no messages, other times, several in a week). But I think you'll find someone there who can answer.
