I thought you might be interested that SiliconBlue finally is offering their
parts in a VQ100 package. I'd heard rumors for quite some time but now it
is in the data sheet. I haven't seen physical samples yet but if they can
do the 63-ball WLCSP package, they can certainly do the VQ100.
See page 47.

BTW, I enjoy Antti's Brain. I'm also working on a Silicon Labs project at
the moment.
