OpenVPN is LIVE and not Alpha. To ensure you understand how to tell the status of an app, we have a wiki page with the details.
http://wiki.amahi.org/index.php/App_release_process
The status is done by OS, so you have to look at the OS you are using, i.e. Fedora 14 or Ubuntu 12.04.
For those in alpha status that you are interested in, they are most likely not finished or not working in most cases. We try to move most apps that are usable to BETA until they can be tested and made LIVE.
We have a long list of apps, but a very small team of folks who maintain Amahi. We are all volunteers and do this in our spare time. We do try our best to move apps along, but sometimes we just don't have the resources.
If there are any specifically you are interested in, please PM me and I can update you on their actual usability. Should you desire access to BETA apps, we do have a subscription with a small fee that many utilize. Please see the web site for details.
