[AGENT++] windows sub-agent, license and compatibility

[Hong Chen]

hi folks,

I'm looking for a toolkit to build a sub-agent which runs on both Windows
and Linux. Agent++ seems promising, but I have a few concerns here:

1. packages
On Windows the master agent would be the native Windows Agent, to build a
sub-agent, the following packages should be included, I guess,
    - SNMP++
    - Agent++
    - AgentX++ (include Agent++ Win32), to build the sub-agent
    - AgentPro ( optional ), to generate the frame work from a MIB

Is this list correct ? Is Agent++ free in commercial use? And AgentX++ and
AgentPro are licensed in commercial use ? If I don't have AgentPro, how
difficult it would be to create the frame work ?

2. Compatibility
Is sub-agent built on AgentPP libraries compatible with native Windows SNMP
Agent?  If it complies with AgentX protocol, it should. But the Agent++
Win32 readme talks a lot about replacing native Windows SNMP Agent with
Agent++Win32 master agent, and running native agent and Agent++Win32 Master
in parallel. If native Windows SNMP Agent and AgentPP-based sub-agent are
compatible, why should one replace the native one ? Is there any success
story of co-existing native Windows Agent and AgentPP-based sub-agent ?

On Linux, if I want to deploy a AgentPP-based sub-agent, the master agent
should also be built on AgentPP or  I can run another master agent like
net-snmp agent? ( net-snmp supports AgentX) Is there any successful story of
co-existing net-snmp master agent and AgentPP-based sub-agent ?

thanks in advance
