  "Wow, plunker seems really nice. You really do make a strong case with the package catalogue."

Thanks!

Server-side processing:

If you make a style.less file and link to style.css from your markup, the less will be transpiled by the preview server. This applies to most compiled web languages (including ES6: script.es6.js -> script.js). If something is missing, I'll do my best to add it.

Collaborative editing:

Yes, this is true collaborative editing thanks to ShareJS [1]. However, at the moment, I have an issue hidden away somewhere whereby a streaming session may be corrupted when several users are concurrently editing. I have been unable to boil it down to a reproducible case though.
