OK, 37 will have this. You'll have to run it yourself (there won't be a top-level excutable for it), but if you were to do:

java -jar jemplode20.jar org.jempeg.empeg.protocol.NetworkEmpegDiscoverer

it would print out something similar to hosts format to stdout (I say 'similar" to hosts output in that the name of an empeg can have spaces, etc. in it, but you can filter that with perl or something if you needed). So it would print:

192.168.1.100 Mike's Empeg
192.168.1.101 Kirsten's Empeg

Is that enough to just print to console? Can you chain commands together to echo it out to a particular file?
