Some observations from this change:

1) The "From Internet" button in the +New tab is right now a complete lie,
and gives un-user friendly error messages. Either you should remove this
button (for now), or somehow make it bypass the whitelist.
2) You cannot ssh out (nor use any services that rely on ssh tunnels, e.g.
sshfs).
3) It seems like only some of *.sagemath.org is whitelisted: you can
download packages, but you cannot interact with the repository at
git.sagemath.org.
3b) Because of 2, you cannot contribute to sage development.
4) It makes working on the distribution part of sage (whether reviewing, or
upgrading packages) pretty much impossible at the moment.

At the very least 1 and 3 should be fixed ASAP (and not wait for this vague
"quota" thing).
