Windows "Senate Judiciary Committee staffers plan to take a look at allegations that Microsoft has made it difficult for competing Web browsers to run on a certain version of Windows, an aide to Antitrust subcommittee Chairman Herb Kohl told The Hill Thursday." Good. We have to nip this in the bud, and with a bit of luck, it alerts Washington to the iOS situation as well. More browser competition equals a better web - mobile devices aren't magically exempt from this just because they have no keyboard. As simple as that.

What about forbidding memory to be RWX, but allowing it to be either R-X or RW-, and letting software dynamically switch pages between both protection modes through system calls ?

This way, one both allows the existence of third-party JITs and still gets the full security benefits of DEP/NX. Forbidding the existence of self-modifying code is impossible anyway, since programs can always include a simple Turing-complete bytecode interpreter and read instructions from a data file in order to get the job done, even if it will be slow.
