We're creating a development environment based on a visual object language using a fully composable framework. The output of the development environment is blobs of "hooked up" objects. The user's programs are stored on host servers and, in real time, propagated to all people working on the project. Meta-data and data are also part of a program the user is creating.

We would like to encrypt the blobs of objects so behavior can not be injected into the program (logic can be injected anywhere - think something like Aspect oriented programming to an extreme). We would like to encrypt any data (program - blobs of objects, meta-data and private user data) that is being persisted and/or propagated.
