It's not clear how alive SPIN really is anymore; it would be surprising if
they actually did this.  In the OS research community the word is that it 
is "Spun Down" or anything along similiar lines; work could be tailing off 
on it, although you'd have to ask Brian Bershad to be sure.  There haven't 
been any papers on it in some time, at least not in (for example) Operating 
Systems Review or at the last SOSP. The current US OS hotspots are Utah (Flux),
MIT (Exokernel), and Harvard (VINO).
