I'm not quite sure what's so obscure about the source code of the DCOM
server, but maybe it's the fact, that there it uses some abstraction layer
from R to provide a more generic interface.

One component of the DCOM server is a proxy DLL which is installed with R
and provides interfaces required for the COM server to access R. If you feel
you don't want to use the COM server because of performance issues you can
directly use the proxy DLL instead. This DLL should be enough to use.

I'm not sure what the performance issues you are addressing are. Could you
please clarify.
