I see that JPT tried to address your question in the Linx Club thread.
However, should you wish a more authoritative response, I might suggest posting your question in Dr. Brian Louie's blog at Swedish Hospital in Seattle. It's a simple registration and he usually responds within a day.
Here is the link to copy and paste into your address bar...
Hope this helps you. Let us know what he says!
