.NET application - reopen word at particular bookmark

Hi

There is a requirement to open a word in browser (IE9) at the particular bookmark/page on link click of web application page.

Application Details: .Net 4.5/Asp.Net MVC application

I have the following queries to identify the valid approach that will help me to complete this functionality.

1. In first level, Is it technically fessiable with ASP.NET MVC application?

2. If possible, Can we achive through Interop.Word (sdk) or should be used Open XML?

3. If possible, would throw any threading issues when multiple user access same document (at client-side) since it is server (IIS) based application?

Note: installing word in Server is not possible but every user node will have word software.

It should be veryful if somebode throw some light to procced further.

Thanks in advance.
