Just ten more days until the VentureBeat Mobile Summit, where we’ve gathered 180 of the top movers and shakers in mobile we could find.

Every one of the 180 invitees is expected to participate in the debate, which will focus on the biggest challenges in mobile:

1) the future of HTML5 (yep, it’s complicated), and we’ll have Google’s new SVP for Chrome, Sundar Pichai debating the future of open mobile development with Facebook’s VP of Engineering, Mike Schroepfer;

2) the future of mobile payments (with NFC, we haven’t seen this much controversy and hype around a technology since the fabled Pointcast of the 1990s);

3) the future of mobile in the enterprise (Apple and other device makers are disrupting big-time, and folks like RIM and IBM are looking badly flat-footed);

4) the future of social and identity standards (we’ll hear about some new initiatives from Verizon, but lots of others will be at the table, including Zynga and Groupon);

5) the future of the mobile economy (advertising sucks on mobile, so other methods are desperately needed to make money — and Qualcomm, to name just one example, will preach that cutting edge augmented reality will be one of them).

It’s all happening at Cavallo Point on April 25/26.
