I would start with this, and add more CPUs as needed:

Of course I understand your Socratic suggestion -- Google *probably* has 
better performance for that particular application (search engine) -- 
But you are suggesting that RDBMSs are inappropriate for semi-structured 
data.  I think that is a bit of a stretch, and I think that widespread 
usage of MySQL (to pick one) attest to their usefulness for exactly that 
purpose.

Overall, I still nurture my original hesitations: talking about 
databases in terms of 'statelessness' is nonsensical; and predicting 
that map/reduce data storage will reduce RDBMS to a niche outside of web 
applications is overly ambitious at this stage.

My motivation here is professional courtesy: a little less than two 
years ago, I was told by *someone* (^_^) at PhillyOnRails that 
_continuations_ were the future of next-generation Rails apps.  Oh, the 
time I've wasted . . .

I look forward to your slides, and to CouchDB.  The interesting stuff 
always happens in alpha.

Thanks!
