I gotta say, I loved this idea when I read about it. My house severely suffers from infiltration. Thats why my wonderful R60 attic insulation (bumped up from R20) last year only contributed to a 3.5% reduction in heating. I will be doing this test hopefully in the near future and reporting back with findings.

This house has no exhaust fans, and the ones I've seen are not equal to a blower door. To do a self test, I'd round up three or more box fans and tape them into an open window. Or, I'd just wait for strong winds from several directions.
