Love the idea! want to have anyway one session in the context of the wallet ring focused on wallet interoperability for sure. And we also need this at DevCon4 as perhaps some wallet developers will just come at day 1 and leave at the last day and we do not get them on board in the FEM Prague council before. And this is really needed - just see: imToken 2.0 ethereum: URL-WTF
Would be great if @boris could submit and do the meta talk you have in mind (introduction of FEM, structure, howto events, … ) This can also perhaps get him his ticket as last time I talked to him this was not yet sorted out.
