I fell in "love" with the Citrix product back in 1997 while consulting for ATT, working for PriceWaterhouseCoopers. I have been an evangelist for this technology since then, and have not found any competing technologies that can compete with it in the areas of performance, features and managability. I have developed a suite of applications that enable multi-company/multi-farm support for all levels of adminstrators from a single web interface.
