I think the following code does pretty much what you want:

http://trac.openplans.org/openplans/browser/BlockParty/trunk/blockparty/public/js/mapping.js

(The code's from this project: http://sites.openplans.org/blockparty/)

The code is pretty dumb in that every time the marker is "moved" it removes the
old OpenLayers.Feature.Vector object  and then creates a new one at the updated
lat/lon. It's not too pretty, but it works quite well.

Hope this helps,
  -Nick
