I have recieved 2 prototypes of my design DSPCARD from ProtoExpress.  
It was designed using gEDA and PCB.  It is 4 layer 6mil 
track/space.   I have posted some information about it and pictures 
of the bare board at http://dlharmon.com/dspcard/index.html  Sorry 
about the bad scans.  The BGA part is a FPGA (256 balls, 1mm pitch)  
I plan to try soldering it in a toaster oven.  The board is about the 
size of a credit card.  Thanks to the developers for making this 
design possible.
  I'm very curious to know your results from the toaster oven when you 
try it.  I just received a tabletop reflow oven (a purpose-built one 
;)) and will be attempting a BGA (Xilinx CPLD) in it soon.  Good luck 
with your efforts.
  And I echo your "thanks" to the PCB developers...I sent out two 
layouts yesterday, and I will likely be sending out a third today if I 
can un-wrangle a few traces, all done with PCB (GTK version) on a Sun 
UltraSPARC workstation running Solaris9.
