I hate to say it, but 0.4mm won't work for me. 0.5mm pitch is fine.
It's not about soldering skills. It's about PCB trace widths and clearances.
A 0.4mm pitch device requires a trace and space design rule that is less than 6mil.
This means I can't use cheap PCB services that need >= 7mil rules.
With 0.5mm pitch there are no such problems.
While I do not intend to make "developer" boards, I do have ideas for products, and 0.4mm spacing puts the current P2 plan off my radar.

I'd love to hear more about the process you use to get down to 1.5 mil spacing with toner transfer.

Has any one heard if there will be a QFN available? It would be nice to save a little board space, and get some of the traces closer to gather at the package.
