Some questions about WineConf.

Hello, I'm a Wine user since somewhere around 1.5 (2012, I believe?), and ever since then I got really interested in it. (Of course Wine is not my only interest within the computer space.) Since I don't have deep pockets at the moment, I was really happy to find out that WineConf is hosted in The Netherlands this year, though I have to travel all the way to the other side of the country since I live in Overijssel. Thus it got me wondering whether it would be possible to attend for just one day. I'd also like to know about the ARM Emulation update. Is this about the x86-on-ARM Android syscall emulation or? Because it doesn't say x86-on-ARM specifically. As for my last question: It's hosted at a hotel, right? So I basically register online, and just show my ID at the hotel reception? Just making sure I get the right place and all. Thanks in advance & best regards, Gerhardus Otten
