yep, agree. As mentioned we already agreed about a request+sent
interface like "GET LOAD 1".

yep, that is better as the numeric menu system now.

Please notice that "getload" won't be enough.
The libgomd methods will connect only to one configured gomd.
So if you want to get e.g. the load of all nodes the gomd will handle
this using gomd<->gomd (UDP) connections.
So we need something like "GET/SET [option] [node-id, or node-range]
for the interface.

yep, good idea :)

every network node has a hostname. I prefer the hostname.

no need to yell. You made your thoughts about it and they are more than
welcome and usefull for progressing.

aaah, JP will care about it, hehehe

yep, we need a "docs" target.
