I don't know but I do have to wonder ... if this is a production website presumably it is of some value to someone, and since a dedicated low-end server can be put together for less than $1,000, why not just put up a box to run the site? Most of us experience OpenACS+Postgres+Linux uptimes measured in years, in terms of non-intentional interruptions of service. I just check to make sure my automated backup service has e-mailed me yet another success story every morning and other than that don't touch my machine.
If the site's not worth the few hundred bucks of a dedicated box is it really a "production" site?
