The xpcom package for uuid's does not work in Windows anymore (it worked
before firefox 1.5) and I haven't had time to look how to compile it
again yet. The first time was a nightmare (but used a free compiler). In
Linux there are no problems as far as I know. In case it is easy for
someone else help in compiling the component for Windows and firefox 1.5
Now the package does work but instead of uuid's it uses http addressed
Later I hope to let user's define the http address space if they choose
to use that, I just need to check they use space that they can write to.
