I'm looking for an old copy of the Livescribe SDK. Livescribe have discontinued their developer program, and I've searched far and wide for it, only finding others asking for the same: http://www.kellbot.com/2011/06/livescribe-developer-community-huge-f-you/
I'm envisioning new ways the smartpen could be extended with extra functionality (bluetooth / wifi) for extra scenarios (it could do your expenses automatically, or work with musical staff / stave paper).
I'm trying to get as close to working prototypes as possible, and interested in anyone who is developing with Anoto dot paper, or any other smartpen manufacturer.
I haven't found an SDK for Livescribe, but you might want to take a look at this link: livescribe.custhelp.com/app/answers/detail/a_id/1/kw/sdk
