[boost] Flow-based programming library for Boost?

Is there any interest out there for a library that allows you to create fast, efficient flow-based programs with an easy-to-use object-oriented interface? (http://en.wikipedia.org/wiki/Flow-based_programming) I've created an open-source library that does this, called "DSPatch" ( http://sourceforge.net/projects/dspatch) and would like to contribute it to the Boost Libraries. Please let me know if this sounds like something you'd like to see in Boost. Thanks!
