Peter Mui, the Open Source Community Advocate at GroundWork, was at Red Hat’s worldwide launch of RHEL 5 today in San Francisco. He tells me Red Hat rented a theatre in the Metreon (in downtown San Francisco) for the introduction and flew out the “big honchos” from North Carolina for the launch and lunch.At the launch, Red Hat also announced a new online marketplace called Red Hat Exchange or RHX for short, which goes live later this year. RHX is designed to be a single source for research, purchase, online fulfillment and support of open source and other commercial software business application stacks. The media was certainly interested – read about it here and here. More info at Red Hat’s site here.Many recognizable open source companies, including GroundWork, are part of RHX. Alfresco, MySQL, and Enterprise DB are also involved. Given Red Hat’s leadership with Linux, with RHX Red Hat could be in a position to become the Amazon of open source software.That being said, will they offer free shipping during the holidays?
