Anyone know if seed that has been taken out of frozen storage for a day, then put back in the freezer and remain viable?

Should be fine, as long as it stayed dry. Condensation forming on cold containers/seed is the most serious issue, so it is best to let a container warm completely and dry on the outside before you open it.

Great,our Sentinels group are having a stall today, so any left over packets can go back in the freezer again, the weather is dry(very low humidity)and warm so the packets wont take on any moisture

It'll be fine, I've done it many times with no problems, even with very shortlived seeds like Meconopsis.

I've heard you can, but obviously you would want to do it as little as possible as the freezing thawing cycle could damage seeds in the long run. Instead i put some of my squash seeds in a sealed and tape covered container in the fridge. Might not keep them quite as viable as in the freezer, but almost as good.
The real killer to seed long term is oxygen. I've had ideas to create my own canning jars with a connector and a valve to use a vacuum pump for storing seeds really long term. A vacuum should work well. Since plants breathe CO2, a CO2 filled container might work even better. But this is all speculation on my part.
