I'm very familier with this. I just deployed a new daemon I wrote in
c++ for my work. However, this time I'm writing a more complex network
protocol translator, and since I have to write half of it in java
anyway, it would save a lot of time to write the translator in java
too.

I had mainly considered 1 and 3. However, 'posix java' is turning up
good results on google. 'java daemon programming' mostly turned up
results for the setDaemon method in Thread. I was hoping that the
tomcat code would be a good implementation of 1 that I didn't have to
write all of.
