I believe I read that there is a problem with remote actions
to increase entropy. If the install is being controlled from a remote
keyboard, then the wiggles of the user at that keyboard are de-randomized
by transmission to the remote location, and therefore don't increase the entropy.

If entropy is less than min entropy does TUI hang forever? It looks like it.
Should these users instead be given some way to escape? It seems like there
is nothing to guarantee or even make likely that entropy will increase up to
the minimum.

Also, is it really necessary to show the user the percent of required entropy in TUI once
enough is reached? It's hard for me to imagine that that's a point at which they care
