Core team as in people physically in the one location within the same time zone who can solve problems in person. As someone who works for a company where people are moving about it does work most of the time and quite well, but the time zone differences can sometimes be frustrating when you need an answer on something important the other person is sleeping. I understand some places might not have a core team, but a lot of places do. Sometimes it is required to have people you can physically talk to, Internet connections can be unreliable as can Skype and syncing files across the country or world can sometimes hinder progress if one or the other have slow Internet connections.
