Good or bad news depending on how you look at it: Gonetz is out of time and money, and he can't keep up with development of GLideN64. He also refuses to release binaries or source code until the plugin is complete. He plans to make a Kickstarter for the plugin, if he can raise $10,000 USD on a short amount of time, the plugin may be released at the end of 2014/early 2015. If the funding goal is not met (or if the campaign can't be started), the plugin will never be released. Donors would get beta access to the plugin.
(I would kiss this project goodbye. How about making a DirectX 11 plugin based on Direct64, death--droid?)
