OpenVBX

The open-source nature of OpenVBX can be a little confusing. Like WordPress, OpenVBX is a downloadable software package that you upload to your own server and are free to tweak as much as you’d like. However, unlike WordPress, which offers a hosted solution at WordPress.com, Twilio isn’t offering a hosted service yet (though it’s quite obvious that they’re working on launching one in the future). For the time being you’ll have to host it yourself, though Lawson notes that Dreamhost currently has a 1-click install setup, which should make things pretty simple.
Of course, OpenVBX relies heavily on Twilio’s service, tapping into Twilio SMS and telephony APIs. When you use OpenVBX you’re charged Twilio’s normal rates, which run $1 per phone line per month ($2 for a toll-free number) with usage charges of 3 cents per minute (or SMS). Lawson says that it is technically feasible for someone to use OpenVBX with a backend other than Twilio, but that it would take quite a bit of configuration.
Twilio has always been focused on catering to developers, and OpenVBX isn’t any different. While the product will obviously appeal to businesses, Twilio is encouraging developers to take the technology and make it their own by integrating tweaks and plugins. For example, an enterprising developer could tweak OpenVBX so that it’s perfect for restaurants, and then resell it as their own service. Twilio still gets paid through their per-minute and phone line charges, and the developer can charge a hefty premium on top of it.

Free BSD Unix

Free BSD Unix is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. FreeBSD offers advanced networking, performance, security and compatibility features today which are still missing in other operating systems, even some of the best commercial ones.

Dynebolic Linux

Dynebolic Linux is shaped on the needs of media activists, artists and creatives as a practical tool for multimedia production: you can manipulate and broadcast both sound and video with tools to record, edit, encode and stream, having automatically recognized most device and peripherals: audio, video, TV, network cards, firewire, usb and more. You can employ this operating system without the need to install anything, and if you want to run it from harddisk you just need to copy a directory. It is optimized to run on slower computers, turning them into full media stations: the minimum you need is a pentium1 or k5 PC 64Mb RAM and IDE CD-ROM, or a modded XBOX game console - and if you have more than one, you can easily do clusters.
