Why ask to see source for a project above and beyond the work-sample test you've already administered? I think work samples are a wonderful way to screen candidates (really, the best way) but to presume that all qualified candidates will have an additional sample of code (to the scale of a "significant project," even) available upfront for you without requiring an additional commitment seems disingenuous. You end up applying an implicit filter for "developers who feel confident and comfortable contributing to OSS and/or possess copious free time for a personal project," which probably isn't really what you were trying to select for and tends to unfairly filter out certain types of candidate.
