NICE have been trying to go software only for years (more profit in the support). The only solution at the moment that is CFE is a VoiP system, station side recording will always need dac based recording. They had plans to introduce a CFE solution for smaller recording environments, i.e if you need to record up to 90 chs they would supply the s/w and dac cards and you would put them into your own server. Don't know if anything came of it though.
When I was born I was so suprised I didn't talk for 18 months
