Enterprise Mashups?

It's the day before I go to Mashup Camp in Dublin. One of the focal points of this "unconference" will be "the enterprise mashup", which has become kind of a holy grail of web 2.0.

For some time now, I have been trying to resolve for myself how collaboration, mashups, and other web 2.0 buzzologies can really be relevant to my end users who are time-poor, technologically conservative, and only concerned with the bottom line. On top of this, technology in my enterprise world is wrapped in a tight web of permissions, corporate IP, and government regulation.

However, I am still optimistic that many of the technologies and models from the web 2.0 world have a great deal of value for the enterprise world. One of the problems seems to be that many of the guiding principals in the web 2.0 consumer world are incompatible with the enterprise world and need to be transformed. Here are a few:

Consumer Web 2.0 principals

1. Information should be free
2. Users want to interact with the system and use it for expression
3. Build first, monetize later. For example: build up a community of people and then generate revenue through ads.
   

Enterprise Web 2.0 principals

1. Information needs to be monetized
2. Users want to use the system to do their jobs. They don't want to put anymore information into the system then their current work flow requires (and less would be even better).
3. Everything must begin and end with a business case. Advertising is not a relevant business model for premium enterprise applications, which must demonstrably cut costs, generate more revenue, or both.
