OK. I am developing something similar and here is what I do: 1. For db, it really depends on the level of security and you app architecture. I am planning on different dbs for each paying customer. 2. Use a template engine like Jinja(Python) or Mustache(support for a slew of languages). 3. Python/Flask is good. I looked at both Flask and Bottle but I decided to go with something else that fits my needs. If you want PHP frameworks, there is FuelPHP, Kohana, CodeIgniter, etc.
