Cordless trackball

[ecom]

Anyone know of a cordless trackball similar to Logitech Marble trackball? Or perhaps some kind of wireless USB tranceiver?

Must be functional from 10 ft away.

The ball must be manipulated by fingers so no thumb manipulated trackballs.

Don't think there is one. Check at Newegg.
