Some of these seemed pretty 'expensive' to get into... the use of ASICs, 
and the like, also, they seem to be directed to pretty
specific implementations of transmissions, even though one could 
conceivably load in a new chunk of firmware 'on the fly' perhaps...

Looked interesting, but did have this overhead of ASIC, and buying the 
attendant boards.

Looks closest to what I'm doing... albeit not with a PPC core...

Almost instant negative... I have my Master from UCSD, the consolation 
prize for those who didn't get a PhD... and further... have not 
forgotten the nonsense with UCSD Pascal and the Regents... but I digress...
