Agreed on all counts. As for the backgrounding stuff, though, don't worry too much, as with a local binder, services become little more than classes running in the background. The ickiness from all that AIDL stuff I've found to not be particularly necessary, as you won't have other applications needing to access your service, typically. Exporting content providers to other apps doesn't seem to be particularly useful, anyways, unless you're Facebook or OEM, where apps might reasonably expect to find the content provider or service they're looking for.
