For my applications I will have access to larger 686 systems so drive space, memory, etc. is not an issue. I wondered aloud if anyone has made a "kernel module"  system for an RTEMS based core system? Dynamically loading code segments to allow for remote system development. What are the pitfalls and advantages this might bring to development?

The Runtime Loader project provides a dlopen etc interface to loading 
code. It is still in development so some issue exist and possibly more 
may be found but it is usable.

The target side is held in a repo here ...

and the host RTEMS linker is held here ...

Some doco is here ...

and here ...

If you need anything more please ask on the lists or IRC.
