Silverlight

From Wikipedia:

Microsoft Silverlight is a programmable web browser plugin that enables features such as animation, vector graphics and audio-video playback that characterize Rich Internet Applications (RIA).

To host silverlight content on Dreamhost, you just need a modification to your .htaccess file.

Add the following to your .htaccess file for your domain and upload the correct Silverlight files.

AddType application/xaml+xml .xaml AddType application/x-silverlight-app .xap AddType application/manifest .manifest AddType application/x-ms-application .application AddType application/x-ms-xbap .xbap AddType application/octet-stream .deploy AddType application/vnd.ms-xpsdocument .xps

If the client has the Silverlight plugin installed in their browser, the RIA content should show up fine.
