This can be a good option for situations where the speaker can't move a

The upload from Prishtina has finished, it is under
vittoria.debian.org:/home/pocock/2017-10-07-prishtina
I've started to receive slides by email, I'll rsync them to vittoria
when I have the lot.
Can you suggest how volunteers can retrieve and play with these files
now? I'd like to notify them on the FLOSSK list (Kosovo) and Open Labs
forum (Albania)

Daniel
