Yes :-) I just wanted to point out that I have some knowledge of the 
LLVM infrastructure and that I was using the JIT for my own project 
quite substantially. While there are many areas where still need a lot 
of work to understand, I am very interested in projects like yours and 
so I just wanted to ask. LLVM lacks symbolic information (hence 
lowlevel), which makes it impossible to be used as a first class IL for 
a project like pypy. I will have a look at your IL.

Never mind. Thanks for your reply.
