Maybe not, the very fact that we are using linux on an FPGA makes these 
philosophical questions worth asking (and possible to be answered!)

Now I *will* get off topic :)

I'm not convinced that we will ever be able to run the source for, say, 
the boa webserver, through a translator, and get some detailed low level 
RTL circuit to synthesise.  What does malloc() mean in hardware?

Well maybe that's not true, if you give me the boa source, I'll generate 
a hardware description...  it's called a microprocessor operating on 
stored opcodes, with a memory subsystem, and ...  :-)

What is hardware?  What is software?  Are they really distinguishable? 
Does it matter?
