I'm involved in communications systems and services and am totally in favour of open systems software. Although I'm not actively involved in coding and writing software systems anymore, taking more of a R&D and directive role, I've been involved in many projects and developments in fields ranging form communications to the hospitality industry to medical aid systems. Also created law.za country tld and currently consulting for IMB in Cape Town.
