Perhaps not the best name - we want to be able to both read and write,
and it's not clear which way copy goes.  I don't want to end up doing
magic thinking that ``this looks like an address, not a filename'' to
figure that out.

Perhaps read/write?  But that's still not clear which way is which. 
load/store would be perfect but load is already used.
