The Access Grid Toolkit 2.3 RPMS for Fedora linux are available at: http://www.itee.uq.edu.au/~agn/ag_fedora/
Experimental support for Shared Presentation and Shared Browser is available with this release. For most trouble free operations (if you had an older AGTk previously installed) I would recommend having a fresh ~/.AccessGrid dir before setting up AGTk2.3 to your liking. But first back-up any existing identity certificates by exporting them to a file, then rename ~/.AccessGrid to .AccessGrid.bak or whatever. After starting the VenueClient, import your certificates. You can also copy your old "My Venue" bookmarks file (.AccessGrid.bak/myVenues.txt) to the new ~/.AccessGrid directory. Cheers, Doug
