You're assuming that it was his plan and his decision to focus on the iPad. Kahn will be his employer, so I imagine they have a hand in deciding what is important enough for him to work on. It doesn't seem likely that he just up and decided that he'd build them an iPad app and made the decision without needing any approval.

Roughly right. I told them that I really wanted to build a cross platform, mobile, version of their application (amongst other things, naturally). They mentioned that they were already looking to build an iPad application - that seems like a fine place to start development and testing.

It's going to be a challenge to figure out the right UI idioms for the project, less so getting it working on a bunch of platforms giving the technology stack (open web technologies). Right now that's my biggest concern. Once we figure out how the interactions should work then the table/mobile world is our oyster.
