This is a useless thing I made on a whim, but here you go. InkyDoc, a Google Docs add-on that lets you write and play Ink stories directly in Google Docs. Try it, let me know if it works for you. Inky Doc Add-On
Code is available on Gist. It's based on inkyjs, Ink's javascript port.
All the info is also available on this cute little website I made.
