is there a linux running on jvm arch ?

is there a linux running on jvm arch ?

[FORT David]

I 've tested the User Mode Linux a few times ago, and it gave me an 
idea: given the fact that we had a GCC which
produce bytecode from C, it would be possible to produce a port of 
linux(a new directory "jvm" in the arch dir) which
would run in a Java Virtual Machine. (after some inquiries such compiler 
does not exist :-( )
I'm dreaming of a linux booting in a browser applet(imagine sending such 
thing in a mail to MS peoples !!!!)

The JVM is very very bad from a C language point of view. You can convert C
code to it and there have been some very experimental demos of this. However
it is a very non trivial problem

Note that PicoJava is basically the JVM with a few extensions to run C
code reasonably.  It might be a better target.

If you really want to help the MS peoples get Linux, consider a straight port 
of UML to Windows.

I've been trying to encourage someone to do this for a while, with limited 
success :-(  Enough has been done that I think I know what the main obstacles 
are, and I think I know that it's possible.

So, if you're interested (and have the appropriate Win-fu) let me know, and 
grab the code and start porting...

While I am not sure if this is possible with Linux, something like this has
already been done with Inferno.  Check out:
