well, I basically want to avoid the impression that this is a phone network for
reliable use for everyone. The software will not run stable enough, and I
suspect many interoperability reasons. Also, our capacity is too small for the
number of people at the event.
"stable" means that this is not where we should test each and every of our
committ's, but rather run something that we expect to behave as sane/stable
as possible.

I don't really know yet. I'll ask the HAR guys how early we can start to put
up our equipment.

Don't count on any equipment being there for us. I'll bring my own personal
tent (well, it is a tent intended for 5 people AFAIR), but that's it.
If we start to ask for support from HAR, I think this will in turn raise the
expectations that we actually provide a stable operational service for them -
something that I think we simply cannot provide yet.

well, those SIM's would have to be sold, and that would mean dealing with cash,
dealing with change, etc. - not very practical IMHO. Also, if we sell something,
that again leads to the conclusion that people should get something in return.
It might also raise the wrong impression to the regulatory authority if we actually
charge money for anything.

heh. well, we can have a simple script that respawns the two (in the right
order) if bsc_hack dies. We should have 'ulimit -c unlimited' and store all
the core files for later debugging. Also, the pcap files have to be rotated
away at every bsc_hack restart.
We also need to ensure that we save the bsc_hack binary that corresponds to the
respective core versions. Maybe actually the entire corresponding source tree
for gdb.
That would be a task for our pre-HAR TODO list (I'll start one soon).

Well, I think it is always good to have another unit, and if only as spare part
in case one breaks or magicall disappears. Apart from that, it might also help
for testing BS-11 specific code on something that is not the production network.
Regards.
