WorkshopLive.com is a virtual music school that features dozens of professional instructors teaching lessons online for all levels of expertise, in guitar, bass, keyboard, and drums. When WorkshopLive was in the early stages of development, the company had limited funds to devote to hardware, software, and human resources, so CTO Marilyn Hoefner decided to give open source software a try. "We’ve been extremely happy," Hoefner says.
