Hi Duncan! I know we're late to the party. I work at Ajour Systems and we have just launched our newest tool, AjourObjects(), which I believe does (at least some) of what you've requested.
* Well structured lists og types and families including views of their meta-data synchronized
Heres a preview of the way we structure the lists of families and types:
* Multi user environment
With our web platform coming soon and our Revit plugin, you already now have the opportunity to work with your entire team across continents with AjourObjects.
* Simple user interface
Heres a few images of the UI:
* Quality Assurance tools for the BIM model (does the data in the model fit the data in the type database)
We sync all data on objects between your project and the database at all times ensuring that the data is connected. You also have the option to chose the synchronization direction of each individual parameter (say, you want some data to only flow from Revit to the database or you want some data to only flow from database to Revit.)
* Access to standard data such as classification and property sets
We have built in classification systems but also allow the users to create their own grouping of objects.
* Possibility for flexible sorting of information
You can filter and sort all data as you wish:
