Hello

Just an idea

- extending nrpe to be able to support builtin commonly used checks (ping, load, mem, disk, etc ...) and support permanent connection to Nagios (over Unix or TCP sockect)
- make Nagios support directly this new "super" nrpe as dl module

Security and memory management problems should be easier to fix, or at least have a lower impact if limited to nrpe.
