It isn’t Basternae, but I have the freely-downloadable Magma 3.04 codebase running on the new Linode server. You can connect at basternae.org port 4001.

It’s all stock zones, but at least there’s a demo site running. I can’t guarantee that it’ll be online all the time, but it’s up now. With nobody online, it uses 0.1% of the CPU.
