The idea is to basically replace Access.
We'd have a PostgreSQL back end, with classes and fields pulled dynamically.
The front end would use things like SimpleForm for building forms, but dynamically instead of hard-coding each row's details.
Pros
Large potential user base.
Lots of possible ways to charge.

Per DB
Custom installations
Could turn into a real startup.
Could do a Kickstarter to raise funds.
Timing is probably right.
Cons
Might be challenging to implement well.
Might be more JavaScript than Ruby.
Could turn into a real startup.
