Eric-
Good to hear from you! Their was a Lindahl designed "A" cat in the '80's that was almost literally an "upside down hull" design w/ intention to plane and there was a production planing cat- I believe it was a 16 footer even- not very popular- sold here in the US. I of course can't remember the name right now. I also recall I think it was Wouter posted about a new cat in Europe that had planing steps in the hull and was supposed to plane, I believe he saw it at one of the European boat shows.
Here's an interesting link from the designer of the cat video you posted-

Or get an inflatable that one that claims it easily enters the "planing state"-http://www.maelabs.ucsd.edu/mae_guides/presentations/examples/Catamaran.pdf
Even the venerable AquaCat is claimed to be "planing"- "Featuring wide, flat bottom hulls with turned up bows and a small keel skeg, the pontoon design is unequaled in weight carrying capacity and planing speed." !!
