Christof/Ignacio/all,
I am near Stuttgart (to be precise, Porsche is just at my doorstep here

) then, so unless the F2F was only accessible to people at ECE I would be happy to join you at least for the second half (after Lunch) of it.
I help a PolarSys member with M2M and an Embedded Real Time project, but the schedule is quite busy so even if I was actively involved in any of the sessions my proposed co-speakers like JSR 354 Spec Lead CS or others would have had to do most this time. The company could have somebody from their HQ join ECE but even the only PolarSys related presentation accepted for ECE is a project they are not actively involved in, so there is no official duty for me at ECE the client would spare me for

The venue is close and meeting you for the first time in person especially given my involvement with e.g. OpenXC (it was not found relevant enough yet for Automotive to be presented at ECE, to be honest it is still a bit of a "test balloon" so maybe in a few years it might change

) or other Embedded, Automotive or LocationTech projects might be worth a chat.
Should you meet "behind closed doors" at least for those with no time or need to attend the conference, I'd be happy to have a chat and beer with you nearby. I'lll certainly mark the 28th as the most promising date to visit Ludwigsburg...
Cheers,
