I think immutable versions is really critical for having all three of
distribution, coherence and simplicity. 

[Colin said something about versions being content addressable instead
of URL addressable, freenet style]
I dunno. Seems to me that having a url back to where the version was
published is nice. Especially since this makes the source of a package
verifiable - compare it to what it claims to be. But also because it
allows a form of discovery we dont have now, which is that I can find
all the repositories whose changes get into Gorans SMBase line, and
decide to track them myself. 

This all applies to content addressable scheme, except we're not using
such a medium now. Lets get the benefits now, and discuss the perfect
medium later...
