I have written a Dreamhost API application that dynamically manages the size of the memory of a Dreamhost virtual private server. Having recently moved to a Dreamhost PS myself I initially started building this for my own use, however I am making it freely available to anyone else who may be interested under an open source license.
For more information and to download this application see: Dreamhost PS Manager.
The application resizes the memory of a Dreamhost PS based on actual usage and can optionally allow you to follow the resizing of your Dreamhost PS via Twitter.
If you decide to use or try this application, I’d be happy to receive some feedback as to your experience.
