If you want to transmit the result to the server immediatly, that's the 
only solution currently.

The point of each 'fusioninventory-something' is to run the 'something' 
task directly, and send the result where you want. With current release 
(2.3.1), those executables are only able to print those results on 
stdout, but for next release, they'll be more versatile. It means you 
have full local control over what to run, when and how.

When you run 'fusioninventory-agent', on the other hand, it contacts 
each server in its configuration, and ask each of them what should be 
done. Unless you use --force, if the server doesn't ask for an 
inventory, the agent won't run an inventory. It means that agent 
execution control is both local-controled (you decide when to run the 
agent, and for some tasks, how), and server-controled (the server decide 
what is run, and for all tasks but local inventory, how). This is ugly 
and counter-intuitive.

The goal for the 3.0 release is to enforce a better separation between 
local and server-control, by reducing the 'fusioninventory-agent' to 
something that is fully server-controlled. But so far, we've not reached 
this point...
