1) could be fixed in the documentation - "ZFS should be used with caution on machines with no ECC since random bit flips can cause unrecoverable checksum failures on mirrored drives". Or "ZFS isn't supported on machines with memory that has no ECC".
What problem are you looking to solve? Data is written by application software which includes none of the extra safeguards you are insisting should be in ZFS. This means that the data may be undetectably corrupted.
I strongly recommend that you purchase a system with ECC in order to operate reliably in the (apparent) radium mine where you live. It is time to wake up, smell the radon, and do something about the problem. Check this map to see if there is cause for concern in your area: "http://upload.wikimedia.org/wikipedia/en/8/8b/US_homes_over_recommended_radon_levels.gif";.
