RFC: Calendar plugin

Hi,

 I need a calendar thing for our wiki and I'm thinking about the
 interface with the users.

 What *I* need is a calendar that can be displayed on a specific page,
 i.e. not a widget.  In the way I see it, a WaflBlock would work best.

 Now the question is how to input data.  One option is directly in the
 WaflBlock, with a syntax like (please comment!):

    2005-06-10 KwikiEvent in Squeaky Town
    2005-07-12 [Kwiki meeting at Kwiki hall http:?KwikiEvent]
    2005-08-1:2005-08-3 KwikiGathering
    [email protected] [KwikiGathering clean up! http:?KwikiGatheringCleanUp]

 The problem I see with that is that it could get unhandy quickly.  On
 the plus side, all the *content* is kept inside the database, which
 means Archive plug-ins just work.

 Another option is something akin to Kwiki::Attachments, with a
 plugin/calendar directory which would keep the per-page calendar data
 and a special action to add and remove data.

 Another question is how to browse the calendar if it's a WaflBlock.
 Can I put an arbitrary parameter in the URL?  Something like
 "calendar_month=2005-02".  Then I could add "previous" and "next"
 buttons to the calendar.  Along the same line, I could turn the month
 view into a year view.

 How does this sound?
