Hi John,

I meant "obscure" in the sense that very few people outside of the academic
circle of sensor networks will have knowledege of it, or even care to learn
it, which is a big factor in the commercialization of the technology of
sensor networks. Working engineers don't want to take the time to go learn
NesC, which they will have to do to even use TinyOS. Since NesC is a
superset of C, all of TinyOS and applications on top of it can be
implemented in plain C. NesC is not a requirement. This is a factor in the
creation of MantisOS as a sensor network OS written in plain C. This shows
that it can be done.
