This paper introduces a methodology to performs link layer network mapping. As far as I know this is the most generic method to do so. It relies on Variable Packet Size capacity to infers the number of switchs present on the network. It is nice because it does not requires switch to have SNMP agents. This method does not work on other network device than store and forward switch, such as hub for instance. The paper provide link to various implementation that use VPS discovery algorithm. This paper is part of the PAM 2005 workshop and was written by Shane Alcock (University of Waikato), Anthony McGregor (University of Waikato), and Richard Nelson (University of Waikato).
Using Simple Per-Hop Capacity Metrics to Discover Link Layer Network Topology (pdf version)
This paper describe a system called GeoTracker. This system use geospatial representation and temporal (chronological) presentation to provide a new RSS layout that departs from traditionnal layout paper presentation.

They build a middleware plateform called, MxM that is integrated with the MIRACLE multimedia content platform.
They identify the location of the RSS post by looking at the text for know place such as USA, France, NYC. They use the first one found in the post. Once the localisation is done they present the result on a world wide map. Google map in there examples.
I found the idea of using geospacial information and chronological data is useful for enhancing RSS browsing. I think that a new RSS standard that provide them in a specific field will be way more effective than looking at the text. I know that It will add complexity to the RSS standard but optionnal fields with semantic information will really help to improve navigation.
The best part of the paper for me is the use of chronological information to link RSS to soccer video (see the figure). It allows to put information on the video timeline in an automatic fashion. Soccer game is a perfect application of such idea. It might been applied also to conference. For example the Mr Job Keynote always generate a huge amount of posts.
I only regrets that the Miracle engine was not testable.
