You could try out webfaction.com; It offers a control panel where you can add as much apps as you want (including Django, RoR, static PHP, Worpress, etc.). The only 'real' limitation you have is memory usage. I have about 15 different apps running on the smallest webfaction acocunt and it works great; comes cheap too and you don't have to update it because it's a virtual server but it is maintained by webfaction (not your version of RoR, but the system itself). If you take the cheapest package the price is between $5.50 and $9.50 a month depending on how long you want to use it.
