Regarding Rio,

I wouldn't describe Rio as stable just yet, I would still mark it as 
'alpha'. It is definitely usable and Damien is being keen including it 
in his development universe.

Recently I have been hacking Rio about like there is no tomorrow, in 
order to support Windows, which it now does.

The current versions are Rio-Kernel-kph.83 , Rio-Grande-kph.12 , 
Rio-Test-kph.40

Now that LocalFileSystem support is fairly well defined and tested and I 
am moving on to look at other things, namely supporting ZipArchives and 
Remote servers through the same API.

regards

Keith
