Open source is getting lots of popularity and if you are an entrepreneur you make some good money too. HylaFAX is an enterprise-class system for sending and receiving facsimiles as well as for sending alpha-numeric pages. The software is designed around a client-server architecture. Fax modems may reside on a single machine on a network and clients can submit an outbound job from any other machine on the network. Client software is designed to be lightweight and easy to port.
iFAX, a commercial company that is built on open source fax server software HylaFAX, was recently included in Inc. Magazine's 2007 list of the top 500 fastest growing companies in the United States. iFAX founder Darren Nickerson says one of the keys to iFAX's success has been its commitment to the open source community behind HylaFAX. "Our success is tied to the openness of the software."
