Citrix Systems (Quote), known primarily for connecting remote

“Software streaming means now they can extend their presence into the
client, which goes into a whole different ballgame,” he told
Margevicius warned, however, that now that Citrix has entered the

competition. “The services required are different from what they were doing before,” he
