Or an SSH client, and run all that stuff at DigitalOcean.
Plus imagine the cases where you don't have wifi (train commute, metro, lousy coffee shop etc.)
It's probably closed-source, but I use JuiceSSH and it is great. The Pro version has a cloud backup that makes SSH migration a breeze.
I've heard juicessh is great, but I'm not going to use a closed-source app, especially to manage my ssh-keys. I have my own migration method (svn repo), that works great on laptops, it just sucks on android's shells.
You may also need a busybox installer app to get things working.
I also want to be able to configure my tablet from within my shell, and that means I'd have to be outside of the chroot.
