Still not sure how CYMA software would work on an isolated, stand-alone system that has no Internet or on-line connection. Even if the company works solely via an Intranet, totally isolated from the Internet, it seems to me there would be a need for networked communications so the employees could enter their hours, check their PTO balance, etc. But for sure, I could be totally missing something.
Still, with only a couple having small offices NOT in the home, all of my clients with home offices absolutely rely on the Internet. Especially those who still (or again!) have students living at home.
