To answer Matt's question, right now we need about ten IDs. We might
need five more next year.

Do you foresee 0-127 being inadequate for applications and protocols
not provided in the TinyOS distribution?

One other issue is protocols in contrib - we can suggest that those
also occupy a certain id range, perhaps a subset of the range reserved
by net2. Although there will be no mechanism to patrol those contrib
protocols to conflict each other, but at least the applications will
know what range is safe for them.
