Very cool but a far cry from an actually usable open source hardware receiver. Implementing the RF front end is not at all trivial and highly dependent on the manufacturing process, which is probably why they didn't release one. There's also the issue of fabs all requiring NDA's for their PDK's (process development kit), and transistor-level netlists would probably leak some of that information. It would be great to see an open PDK at something like a 65nm or 40nm node which would really allow for open source hardware design.
