If it where that simple.

Regarding availability of the iLotus M12M see this on Synergy:


Availability: Get it while you can, it's going away.

It looks like you will have to consider using LEA6T or something like 
that soon enough.

I like the "openness" of the Motorola and Novatel receivers. Which 
modern receivers provide the same level of openness into states and details?

Oh, we should make sure to backup documentation on the Oncores. The 
early ones is already fuzzy.
