lxrun was a user space application. It emulated Linux syscall behavior via a 
signal handler for SIGSYS (Bad syscall). 

lkp is implmented inside the kernel.

I heard that some Sun engineers did not like janus because it made Linux 
application integration too easy and so they have been in fear that nobody 
would create native Solaris applications.

It should be possible to use the lx brand code to implement something like lkp.
