That reason makes Apple look worse. The example of PGP is silly. PGP is an open protocol. The user can control their own encryption. Apple like Adobe wants to take an open protocol for streaming, in Apple's case RTSP, and make it proprietary. And like Adobe they are finding this is not so easy. The more they seek to exert unreasonable control over how people use devices they have already paid for, the more motivation they give for people to find workarounds. There are benefits to everyone in having open protocols, as the thousands of examples in the RFC's demonstrate, but the only benefit of the "AirPlay" protocol is to Apple. Making devices that can only communicate with other devices you make is dubious business where networking is concerned. It just make everyone's life more difficult- except Apple's. You can't blame people for trying to get devices and accessories made by different manufacturers to work together. RA should not even have to jump through these hoops. These devices that Apple makes should be able to network with devices from other manufacturers. We do not need an "AirPlay" protocol controlled by one company.
