A full size working prototype of the HTS magnet has been built and tested successfully. There are plenty of papers about it. For instance see here . It is still cooled to very low temperatures but less cold than conventional superconducting magnets. They claim this is good enough for their designs.

I know they say they are leaking "two pounds per day" but do they mean they are losing that mass of air per day or do they mean the pressure is dropping 2 psi per day?

The volume of 2 pounds of dry air at STP is about 1/1000 the total volume of the ISS. A loss of 2 psi (out of 15 psi) is more than 1/8 the total air. One of these is a much bigger deal than the other.

It's almost like a virus.

I was at a physics conference a while back and someone worked out that a very large percentage of the people in our subfield have Erdos numbers between 3 and 5. It turns out one of my colleagues also did semi-amateur acting and has an Erdos/Bacon number of 7 - the same as Carl Sagan and Natalie Portman. It's a fun thing to do over beers, but not much more than that.
