Abusing wimlib's pipable WIM format allowed me to build a Windows PE-based installer that deployed a WIM to a hard drive... from a tape drive attached via USB. I streamed the entire install from the tape right onto the hard drive and it... worked amusingly well. Anyone want a setup tape of Windows? ;)
