GPS approaches with VNAV vertical guidance

With all the talk about the GNS80 and the Garmin 430 having VNAV and
LAAS capability, I would like to know something. Are there any actual
approaches in use that one can fly, today, that use these features? Do
you get vertical guidance from GPS derived altitude or is it vertical
guidance from altimeter derived altitude? Where are these approaches?

The GPS-16 at HPN has both LNAV and LNAV/VNAV minimums published. LNAV
alone gets you 600 & 1, VNAV gets you another 120 feet lower.

What's a little silly is that there's also an ILS-16 which gets you the
standard 200 & 1/2, so except as a contingency against the ILS being
OTS, having the LNAV/VNAV approach doesn't buy you anything. The big
payoff is still in the future, when the FAA starts publishing LNAV/VNAV
approaches to runway ends (and airports) which aren't already served by
ILS or other ground-based approaches.

I havn't actually flown a VNAV approach yet. When we get our CNX-80's
upgraded to the new software (RSN), I'll be able to try it out.
