Sea&Sea ports on other housings

I currently have a Light&Motion housing for my D100, and (by way of port adapter) I use Sea&Sea ports. I am looking to upgrade my camera/housing and wondered if any other housing manufacturers make similar port adapters for the S&S ports. I'd like to keep as much of my current gear as I can because - in case no one else has noticed - this s**t is expensive! Thanks in advance.

Seatool makes an adapter for Sea and Sea ports. I have one and it works, though you have to mount the ports upside down. Doesn't affect operation at all . . .
