For example, I have a program that contains a function to read a text file and parse it, and I'd like an entirely different program to send what file to use to that program and have it run it. Also, it needs to be able to parse it multiple times, meaning if 5 other apps also send it something.

My first though was a pipe of some kind (network socket, unix domain 
socket, etc) my next though was a pipeline (use the pipe system call 
followed by fork and exec) my next though was memory-mapping/shared-memory.

My last though is I'm glad it's your problem and not mine. <g>
