4/3 has smaller sensor than Pentax APS-C. It would be like using DA un FF body. You'd get severe vignetting or poor corner performance.
And third party lenses which are APS-C/FF usually are available with Pentax mount.

Or is Davide actually suggesting an adapter to use Pentax lenses on a m4/3 body?

Yes , I think it could be a good combination considering the m4/3 is an open standard

don't worry, there will soon be an adapter for any lens mount you can imagine, for micro 4/3 (unless there already is), pentax won't do it themselves though, not likely.

Yeah, if you were referring to mounting 4/3 lenses on a pentax K mount camera, while it might be possible I think you would not have the ability to focus due to the registering distance between the mount and sensor - it would definitely have issues due to the physical lens size like light fall off and vignetting as well.

If you meant mounting a k mount lens to 4/3, well, you can find adapters to mount just about any kind of lens on 4/3 cameras. I have a k to 4/3 mount. The aperture flange slightly contacts the lens mount contacts inside the 4/3 mount so I am very, very careful with mounting the K mount lenses.

That being said, my panasonic L1 with the 40mm pancake is a sight to behold! The k-4/3 mount doesn't have any issues with contacting the lens pins when I use that adapter coupled w/the pentax k to screwmount adapter, so my 50mm f4 smc macro works beautifully (a 100mm f4 compact manual macro is a nice focal length!)
