This version seems to work fine offline on ubuntu 13.10, so I have an
offline obelisk that I can play with :)
Thanks you Amir!

Now the question is how to update the setup while staying offline. For
security reasons, I would like to update it using a CD/DVD. I thought I
would tar the updated files from the blockchain directory and overwrite
that directory on my offline setup, e.g:
cd worker
tar cz `find blockchain -type f -newermt "Mar 23"` -f
~/blockchain-update-20140326.tgz

But I get way too many files (probably also old files get a newer
timestamp), so even a DVD is not enough for 3 days.
Any idea of how to do it in a simple and reasonably optimized way?
