In fact, the plan in Paraguay is having Munin nodes on school servers
(and on APs as well), i.e., they will send statistics to the mothership
(I guess that won't work for Nepal since connectivity is a problem
there, thats why I asked about "offline" solution).

Actually, it would be useful to have such stress tests before going to
production (of course it might not precise test but at least it will get
a level of loading). It is in the plan for SSK-1.1.

Incidentally, I followed the quite opposite way in case of replacing
ejabberd for [possibly] smaller resources consumption  :)
It just works for 0.88 clients and there are glitches w/ 0.9x clients
(but it is hard to investigate since 0.9x collab code is not mature).
