It has been interesting to compare the PIC Mesh network architect described in the original specification document for this project with other open mesh network architectures that were designed to have more capability but require a specific operating system (Linux or x86) and a library of drivers to support it.

If anyone knows of other open mesh network initiative that should be on that list let me know.
