Just to throw some two-cents in:
What JP described is essentially what I did when I consulted for
IncrediblePear back in 2008. I built an async REST API service with
Twisted (and cred powering a fairly elaborate permissions system). The
customer was PBS.org. It's what underlies their TV scheduling on their
main site and all the affiliate stations that make use of the main
site's scheduling API. (lots of memcached... they are a HUGE site in
Twisted is a good choice :-) Best of luck!
