This actually sounds more like a job for syslogd. You have a task that generates the data, and uses the logging facility to broadcast it. Then you could put a few different computers on your network, each monitoring the log and filtering out what they want, writing the data to the results files.

Of course, it's quite likely that you won't get syslogd to write the data in exactly the format you want. So in that case, you could simulate it yourself easily enough with sockets. Just figure out what information your clients will need to decide which file(s) to write the data to, then box up your data with a prefix containing that decisioning data. Your clients can then read a configuration file to decide how to determine what data blocks go to which files.

I don't know POE, I've never used it ... but from what I've heard here, it sounds like an interesting way to get started...
