LimeWire for MacOS9 is almost exactly the same code, as it is for any other system. - So I guess it's well written after all, - but there is no really stable Java Runtime Environment for OS9. The MRJ definitely sucks. It's equivalent to Suns JRE 1.1.8, while 1.4 is the most recent version and 1.3 was released more than a year ago.
