How did you intend to monetize this idea?

From the application:

We will sell plans that offer version control hosting, testing environments, and easy web hosting tied into the IDE.

Similar to what github is doing, now that I think of it, but with more integration into the online IDE.

Seems like a language-agnostic heroku. Hmm, gotta wonder which would have been the most appealing.

Sell access to it I would expect, or offer a classic Freemium model with features free and higher level features for cost. Just a guess though.
