Server-side VSTO scalability and licensing

I want to use VSTO for creating Word and Excel documents in an ASP.NET application.

Will this scale, or it will create a Word/Excel instance in the background as the old Excel/Word COM Automation model?

How is the licensing? Do I need one Office 2003 license in the server?

Thanks

Yes it will scale. No you do not need Word or Excel on the server to read or write the cached data of an existing VSTO document. I am checking on the licensing question.

Thanks Paul.

However, the wording of your answer opens more questions ;).

I want to create a standard word/excel document. So I can, for example, send it by email.

You refer to the 'cached data of an existing VSTO document'. Are we talking about the same thing?

Thanks

If you are needing to create new Word and Excel document on the server then I don't think that the new ServerDocument functionality within VSTO 2005 is going to help.

The ServerDocument class allows you to read and write cached data to an already existing VSTO 2005 Excel or Word document without needing to automate Microsoft Excel or Word on the server.
