I really do hate how apps hang waiting to phone home to Apple though. It compromises the user experience. (Though I'm not sure how much of that time is actually waiting for slow network services and how much of it is waiting for slow local processing.)
Given that revocation is rare, I think I might be willing to forego online validation and just use something like a local list of revoked code signing certs that is updated at a configurable interval.
