Bluehost no longer offer Oxwall as a standard install.
I had to in the end as I'm running an Oxwall project as well as 3 other projects and the resources they all use is immense. It wasn't fair on everyone else who was on the shared hosting. ^_^
I won't say there were never issues from time to time but they were very helpful and cooperative. With any shared hosting you are vulnerable to others on that host who might have a runaway script or something (which could happen to any of us, eh?)
