socket programming on RTAI

Hi all,
    I have an IBM440PC based board with Linuxppc_2_4_devel on it, and rtai 
ver 24.1.12. Thanks to this mailing list, I have completed the setup and 
am able to run some simple programs.
    Now, I would like to communicate through the ethernet. My application 
is an RTAI module, running an idle(slow) and a timer(fast) task. In the 
idle loop, I would like to send data out through the ethernet link. Can I 
make socket calls directly from the RTAI task? Or do I have to send the 
data through a FIFO (or some other IPC service) to a user space process, 
that then connects to the socket? What are the possible options? Sending 
it through a user process seems a bit too round about for me! Would be 
great if someone out there points me to some good solutions.

Thanks and Regards
