Recently, I presented at a workshop on telecommunications, open source and mobility at the First Caribbean Regional International Telecommunications Society Conference in Montego Bay, Jamaica. Key points in this workshop were:

• The network's value proposition can be fully realized only if it remains open and unencumbered. 
• Setting up independent, yet interconnected PBXs using Asterisk: small ones with AstLinux, large ones with Trixbox.
• Asterisk and the OLPC project. Setting up local phone networks in villages, schools, communities.
