Very good! That's non-convective mixing or mass-transport (to give it
some important sounding names).

Actually, reminds me of the early days of networking, when one of the
fastest protocols was still sneakernet. I.e., copy a floppy full and
run it over to the other machine, thereby transferring 1.4 meg
relatively quickly.

Yes. And what do you mean 'early days'?

I am working for a very large company where, in my area, there are
still two non-communicating networks, and occasionally data is
transferred by sneaker net. Of course, this is going to be fixed any
day now...
