My understanding is that the intention is "near-term from now." The idea 
is that LAMPS should develop something that you could use, say, next 
year to encrypt email you send so that, 15 years from now when someone 
finally builds a 4,000 qubit machine, they can't dig out your (then) 
14-year-old email and decrypt it.
