可以做到这么几件事情：
1. SVN commits
2. JIRA issue tracker updates
3. Nagios alerts for monitored hosts and services
4. Deployment notices to testing/staging/production
5. Results of automated tests if something bad happens
6. Links to pics from security camfeed when someone opens the office door out of hours
而且使用也很方便：
$ echo “Something just happened” | nc -q0 somemachine 12345M
12345端口的监瑞脑消金兽听是用的irccat这个工具。以后自个弄个xmppcat/jinglecat。呵呵。
其实*nix下n多跨进程通讯、inter-process calls都是通过socket完成的。不过est个人还是喜欢COM这种直接的FFI
