Ad-hoc reporting

Is the ad-hoc reporting available for SQL Server 2005 reporting
services a web based environment or is it an application that has to be
installed?
Thanks
Robertits a clickonce application.
this required that the user have the .Net Framework 2.0 installed locally.
then the reportbuilder application is downloaded automatically without any
install process.
but its not a webbased application. its a client/server application which
use webservices calls to the server to execute andrender queries.
