New GUID technology comparison page

Hi folks, Over the last few days I re-read the specifications of some candidate GUID technologies to be used by GBIF and TDWG. As a result, I've upgraded the technology comparison in the GUID wiki. The direct URL is http://wiki.gbif.org/guidwiki/wikka.php?wakka=TechnologyComparison. Please feel free to make comments and corrections. Cheers, Ricardo
