I would _love_ to do that! I really should try again... The last time I tried (last year), it turned out that, while I could easily port the Pierogi code to Android, the IR hardware could only be reached by using device drivers provided by the manufacturers. I contacted one manufacturer (HTC), and they were more than happy to give me everything I needed to get it up and running on their devices -- once I had signed the appropriate NDA. Unfortunately, said NDA required that no code using the device driver (or, really, their entire SDK) could be open-source.

This is a problem for me, as not only is Pierogi currently distributed under an open-source license, it was originally based partly on the LIRC (although that really isn't the case any more), and more importantly relies upon keyset data provided publicly on sites like "hifi-remotes.com". I don't think there's any way I could realistically convert it into a closed-source app at this point.

Maybe things have gotten better on the device driver front. I should take another look...

EDIT: Well, heck! It looks like main-line Android now has an API for infrared. I'll have to download it and take a look. (Anybody out there have an Android device with IR who would be willing to test? I don't personally own any Android devices myself...)
