It's possible to replace NRPE by SNMPv1/2 or v3 or SSH. NCSA could may
be replace by SNMP informs ?

It could be but what about performance ? NRPE is very fast but not
secure [1], SNMP v1 is slower and insecure. SNMP v3 or SSH are secure
but take some resources.

I made some test with those 4 protocols. To check if a process is
running takes by average :
 -  27 ms with nrpe (with ssl)
 -  62 ms with snmp v1
 - 107 ms with snmp v3 (SHA for authentication and AES for privacy)
 - 113 ms with SSHv2 (authentication by certifcate)
