Rounded Corners on Translucent Form

I have a borderless form with it's Opacity set to 60% so the background
shows through. It looks very nice. But I'd like to round the corners of
this form. All the techniques I've seen so far for creating shaped forms
involve using the TransparencyKey property of the form. But this doesn't
work with a form that is translucent because the form color varies at
runtime based on the background colors that are showing through.
Does anybody have any ideas about ways around this?

What about a custom Region? You could use a GraphicsPath object to build the
desired shape of your Form and then just create a Region object, passing
this GraphicsPath object into the constructor, and assign it to the Region
property of the Form.
