I think IP and TCP/UDP work pretty well... seems like they messed up a bit on the size of the address space. That's what I would call the "internet" (along with some general services, e.g. DNS). Sounds like you are talking more about HTTP/HTML. True anonymity seems a bit hard (when you make a request, the reply has to go somewhere). With regards to the "standard runtime environment"... I'd add true bidirectional communication, and a built in local storage mechanism (though Google gearbox and the flash hack seem to have mitigated this). UPDATE: (fixed some cases).
