The adaptoid likely has more than hardware inside it. They most likely have custom code burned onto a (P)ROM chip inside it. If that's the case, duplication of that isn't a good idea. For one, cloning hardware isn't a good idea (especially since there are patents or at least patents-pending for the adaptoid) but also there'd be copyright issues for the proprietary code on said chip(s).
EDIT: Well looking through the paperwork, box, and on the adaptoid itself (bought from ztnet not an original model) there aren't any mention of patents but still it would likely be a legal minefield.
