I am using a UNIX-like system (Linux). I thought I had seen an example 
that talked TCP/IP in crm114. I guess I was wrong. I just went and 
looked back, it was pipes. I guess that is what I get for relying on my 
memory of crm from about a year ago.

Is it possible to have CRM do mailreaver.cm like functionality in a loop 
or will it only do one such thing per invocation? I ask this because I 
have an idea on how to make CRM act like a daemon if it does. (Loop over 
reading data from a program that does the TCP/IP for it... maybe the 
constant scheduling is more expensive than doing pipes directly with the 
program that would have been the TCP/IP sending.)

That is what I was hoping for, sub expressions.

Thank you,
