Hi Jon,
Wed love to support these cards (there are a few other makes too) but they dont have a SIP interface, nor do they have Windows drivers.
So this is something the card vendor has to do. It would make sense to fire off an email to them to let them know that you are interested in this integration and that they should consider packaging and supporting a windows driver for their cards..... As we all know not everybody wants to run Linux.
