css3 menu with inverse rounded corners - html

Question

I designed a navigation menu which looks like the image here:
I want to code it with css3 rounded corners and box-shadows, not using any images.
Problem is the rounded corner to the left of the first menu-item, and the one to the right of the menu... I call it a "reverse" rounded corner...
It should have to change color on :hover.
Is there any way to get this done in css only? And how?

It's just my first attempt, but I think it looks quite promising.
