Ask HN: Web IDEs with hosted VMs?

I have been using Cloud9 for quite some time but problems with disconnecting etc. are increasing in numbers very, very fast during the past month. I have no clue about what's behind that.

So I'm looking for a new web IDE.

What I need:

Preferrably Ubuntu box with not that much power SFTP and/or SSH access to my own server Doesn't have to be online when I'm not using it 5-15 USD / month

Codebox.io looks great but signups are disabled for some reason. Other options?
