I'm writing a web application that might use Silverlight. Before we get the go ahead, Project Managers are wondering if we can change the install URL for Silverlight so that the install package can be hosted inside a local Sharepoint server.

In other words:

User browses our web app
User does not have silverlight installed.
User is redirected to install package (Its this we want hosted in a local sharepoint site)
User installs from our silverlight package
User is happy camper and now has silverlight installed

Is this possible, or do you have to get the install package each time from MS site?
