Nobody's going to be able to support the K-7 or K-x for tethered shooting unless Pentax allows this with the cameras' firmware. At the moment, if the K-7 is connected to a computer, then all on-camera controls are disabled, and any software on the PC is only able to transfer files - not control the camera remotely. Hence there's no way to trigger the shutter with a PC connected. I've not personally used the K-x yet but believe the same to be the case with that camera too.
I'd really love to see this change - the lack of tethered shooting capability is, to me, the biggest shortcoming of the K-7 as compared to its rivals. There's no real need for remote control of exposure variables or shutter - just allowing the camera to shoot from the on-body controls while tethered would be enough to make the function useful.
That would allow me to set the camera up on a tripod, shoot a bunch of images and have them automatically downloaded to preview them near-immediately on my large, high-res PC display, and confirm whether I needed to reshoot with a minimum of fiddling to either pan/zoom on the camera LCD, or transfer flash cards / connect / disconnect the camera between shots to preview on the PC.
