[boost] Any interest in a library for supporting program reuse?

Hi all, the compulsive coder here again, I've just written in a working prototype of a library for writing C++ programs which can be treated in C++ code like Unix filters, i.e. redirected to and from streams, and other programs. For instance: fstream f("c:\\tmp.txt"); stringstream s; HelloWorldProgram() > f > UpperCaseProgram() > s; Is there any interest in this kind of library, for boost? I am using it for writing test and demonstration programs of libraries, but I think it has a lot of other uses.
