SSRS 2008 : Reporting Services 2008

Had my first experience of installing Reporting Services 2008 last night.

I have 3 observations -

1. It did not require a local MS SQL instance.
   I was able to install it and chose to place the ReportServer and ReportServerTempDB databases on another server.
   
   
2. It no longer requires Microsoft's Internet Information Services (IIS) as a web server.
   
   
3. Report Builder seems to reply on domain security hence I need to build my SSRS instance in the business domain, rather than the development one.
