Hi Bobby,
It's better to either bottom post, or inline your comments as the thread 
gets mangled in the archives.

There is MyHDL that may be of some use: <http://www.myhdl.org/>

"MyHDL turns Python into a hardware description and verification 
language, providing hardware engineers with the power of the Python 
ecosystem."

It supports synthesis from the Python RTL Models:
