I am using SBML (system biology markup language) as a front-end 
modelling language for my project. And for ease of further maintenance 
of the model and interoperability purposes, my project requires me to 
convert it into an intermediate form (MA), which is somewhat assembly is 
structure, as in, each instruction takes the form of <opcode> 
<operand>*. Here I am, attempting to write a virtual machine that can 
run MA, using python. So, it becomes a MA virtual machine running on 
python virtual machine.

My concern is, is it simpler to convert MA to python codes or python 
bytecodes. What are the pros and cons? Assuming that to convert to 
python source code is a choice, I'm thinking that MA virtual machine can 
then read a MA instruction and output the corresponding python source 
codes, but are there facilities in python to run python codes, line by 
line, as it is being thrown out by MA virtual machine?

As a side note, does anyone think that this project might be suitable 
enough to apply for PSF Grant?

Thanks
Maurice
