If nothing else in linuxemu can make a GSoc project, I would like to give=
 NTPL a try.


Is NTPL the same thing as NPTL, and everyone is jus=
t repeatedly spelling their acronyms incorrectly?

=
 



Now I wonder how does Linuxemu work? I guess it parses the linux b=
inary and whenever 
encounter a system call, emulate using Plan 9's =
function. I haven't dig into the source
code, just guess.
