Great news. It worked out finally.

Daniel, Jan and me will also be there. We already have our cards so the problem
with sold out cards did not catch us. I can only speak for myself, but I would
bet Jan and Daniel are thinking along the same lines, we would be happy to help

Great. Covering the whole event with an official GSM network should give us a
lot of fun. :)

When do you plan to do this? We haven't settled for final dates yet, but planned
to be around from 12. - 17. Daniel and I should be able to be there earlier. I
would think it would make sense to get the physical infrastructure in place
before most of the people arrive. 10. - 11. for physical software setup sounds
like a good idea to me. That should give us enough time to have it running
stable from 12. to 16.
What about tents, tables, chairs, etc? Is this something we get from the orga or
should organise ourself? I may be able to arrange a big tent plus some tables
and banks. Taking into account that I would need to ask and we have the
transportation proplem I would prefer equipment already at the destination.

Maybe some pre-registration over a website which feeds the IMSI into the db and
assigns a number? It would help to spread the load of register 3000 IMSIs during
the event. :) On the other hand it would drain time now. Anyway, I volunteer to
help out dealing with people at the event.
Hmm, another idea pops up into my mind right now. Any chance we can get a big
bunch of pre paid SIMs without money on the account? If we would get some 100s
of them we could prepare them in advance and just hand out to the people.

Should be the job for the same people running the GOC (GSM Operating Center) ;)
I've seen on the wiki side that you will bring two BS-11 for the stable network.
Do you think that are enough, or should Daniel bring his one as well. (Not that
I could stop him putting _everything_ into the car for the event.)
