Welcome to MobileRead, nickbogaty!
We're very glad to hear from someone in the IDPF.
Especially when he comes with some concrete details to offer!
You don't happen to know any sort of guesstimate on what sort of time-fram Sony, et. al., might be looking at for Digital Editions on mobile devices, do you? We'd be extremely interested in any rumors you could offer here.
Thanks! And welcome again!
