maybe it is too late for that: at the sprint in Halle @polyester announced that there is a possibility to get a few tickets for ~200USD off from one of the conference sponsors.
Oshane is now 87% funded. We have purchased his ticket since airfare prices will only go up from here. In fact,
we had a scare today when we thought the ticket prices had gone up by $500. Thankfully we found one that was still within the original budget.
