It seems likely that the toolchain problems can be made to go away with 
modest effort.

Another step towards meeting in the middle could build on the "binary 
component" feature of nesC, which was designed to support interoperation 
with plain C.  If some interfaces can be agreed upon, then drivers for 
various devices can be written in C and reused in TinyOS, MantisOS, and 
SoS.  On the TinyOS side some wrappers would need to be written but this 
is easy.  Assuming that multiple sensornet operating systems exist and 
will continue to exist, this would seem to be the way forward.  Note that 
there are several more OSs for mote-class hardware beyond those that have 
been mentioned already.  Rewriting all drivers for all of these systems 
would seem to amount to nothing more than an employment act for graduate 
students :).

If we're talking about reuse of application-level logic, as opposed to 
lower level components, then this would seem more difficult.
