The AD6636 certainly looks like a fast path to get what appears to be 
good performance, quickly.  The FPGA of course is more flexible at the 
cost of higher power consumption and more opportunity to learn/tweak/etc.

AMSAT has a BGA machine on its list for '07, so we'll be able to place 
these parts for prototype work in a couple months.
