At Bit Badger Solutions, we maintain 64-bit builds for two software products - xine and the Lightning plug-in for Thunderbird. These are now shown under “Hosted 64-Bit Software” in the sidebar. You can also view links for each of the categories.
Lightning Plug-In (UPDATE: See this post.) Category Link • RSS Feed
Along these lines, there will hopefully be a new xine (1.1.7) coming soon - stay tuned!
