Inbound feeds using ajax for display

UW wants to be able to read feeds from other sites within Plone. 

• Ability to filter these feeds to only contain certain terms, like bird flu or Cambodia. 
  
• Some feeds would be created by administrators, and some feeds would be created by individual users for their own use. 
  
• The feed view should be available either as a side pane on all pages like the calendar, or as the content to one specific page that an administrator can view.
• This should work in Plone 3 and Zope 3.
• Supported formats: Atom, RSS 1.0, RSS 2.0 - We should support as many as possible, but these are the most common.
• Users should be able to grab a feed from the current site, and display it in a page so that they can gather scattered folders from the site into an area that they set up.  This is a form of content customization, similar to google.com/ig.  The intention is to make it easier for users to view at a glance information on the site that is important to them, so more than one feed should be available on this customizable page.
  

Inbound feed information

• Feed title
• URL
• Number of items
• Refresh interval (Possibly Admin only)

Implementation issues

• How should we handle configuration for adding and editing feeds?  Do we possibly need two sets of configuration, one in the control panel and one as an addable type that regular users can use?
• Should we use Archetypes or Zope 3-style objects?
