people are so conservative about file systems at least the Linux community tends to wait and natter about it for years other things go out very quickly but file systems if someone starts a patent lawsuit about that the work you did can be completely wasted Solaris can be the guinea pig for this thing I will be watching with a tiny bit of interest. As far as the whole pay up or else thing SUN pulled I think we have a legal department that needs some castor oil applied and NetApp seem to be coming foreward with a spoon.
