How to provide Intellectual capital services online?

I would really appreciate it if someone can help provide some information to the questions below:

- Which are the top few companies that provide the intellectual capital (IC) services or knowledge management(KM) service over the Net?

- What type of market information would require to help a IC/KM company to formulate a global strategy on the Net?

- What type of online IC/KM services can be provided or should offer?

- What would be the problems and issues that need to be facing for implementing global web based strategy?

Thanks alot.
