i tried it and it worked ok for some functions and not for some others.
also, it currently doesn't support an allowed clients file or database
table.

there is something wrong in the design of external access to ser.
an abstraction layer is missing between modules and external access
methods.  so each module has to currently support fifo, unix
socket, and also tcp/udp interface.
