Recently I had investigated the idea of a Haiku user emulator. Looking  
at your patch, I see a lot of similarities with what I saw in the  
linux-user dir, but your patch is not an svn diff and marks all files  
as fully new against /dev/null, so it's hard to spot the actual  
differences to linux-user...

In light of getting more userland emulations, do you see possibilities  
to move shared stuff to a new "user" dir rather than copying them to  
each *-user dir? The ELF loading for instance?
