no, you are wrong here ;)
1) you cannot be sure that everybody is using MFS 
2) you cannot access /proc and /dev on the remote nodes using MFS !

On the other hand you are (mostly) right. We are all very happy about the 
cluster-wide /proc filesystem from openMosix and we want to get
some of the informations+values from there too ........
......... but we want much more ;)
We also want to be able to monitor values which are not in the
openMosix /proc interface but only local on every system .e.g uptime

The gomd should/could also act as a replacement for "rsh" and "ssh"
because we want it to execute openMosix-related admin commands on
the nodes (from remote).

The most important part of the gomd-project is to my mind the libgomd.
This library will be for developers to use it in their own programs.
The plan is to have a clean and documentated interface to get
all wanted values from the gomd (from the openMosix nodes)
by using "easy" methods from the libgomd.
We will implement all kinds of methods for getting informations about
every node in you cluster (and the cluster at all) in a simple way so
you do not have to "re-invent the wheel" everytime.
e.g. right now we have (about) 3-5 very nice GUI applications for openMosix
.......... but every app is using its own way (and has its own functions) to
get the values from the node(s).

btw: we are looking into the mosstatd code too to learn from it.

.... and we want to implemt libgomd "plugins" for other languages than C too,
e.g Java, PHP, shell ....

Many thanks for you comments and as you know every feedback 
or feature re-quest is welcome.

have a nice weekend Johnny,

Matt
....... another good reason for the gomd project is that we
all want to learn more about c/c++ ;)
