"TCPA appears designed to maximise the effect, and thus the economic power, of such plays. Given Microsoft's record of competitive strategic plays, I expect that Palladium will support them. So if you control a TCPA-enabled application, then your policy server can enforce your choice of rules about which other applications will be allowed to use the files your code creates. These files can be protected using strong cryptography, with keys controlled by the Fritz chips on everybody's machines. What this means is that a successful TCPA-enabled application will be worth much more money to the software company that controls it, as they can rent out access to their interfaces for whatever the market will bear. So there will be huge pressures on software developers to enable their applications for TCPA; and if Palladium is the first operating system to support TCPA, this will give it a competitive advantage over GNU/Linux and MacOS with the developer community."
