Yes - that's right.
The configure system implicity assumes that all C source files are MIB modules,
but it doesn't actually care. You can include any additional code
files that you
require in this way.
Look at the current code. There are many examples of utility routines,
separate config processing, and other code files that aren't strictly
MIB modules. But they will all be included within the agent in the same
way - via "--with-mib-modules" (either directly or indirectly)

Not necessarily. It depends what is in the file myMIB.h
As I said yesterday:

Please note that last sentence! :-)

All of that is possible - see above.
In particular, please look at the header file
agent/mibgroup/mibII/ipCidrRouteTable.h
It's probably not included in the agent any more,
but it does illustrate *exactly* how to handle the
framework you list above.
