We record to ProTools via an MXL 2001 unidirectional condenser mic. The booth has a talkback capability naturally, and we can phone patch directors/client directly into the booth although we do not have ISDN. (sorry.) We usually send either edited tracks or all takes via dropsend shortly after the session.
We are regularly asked to obtain and clear music rights for various productions. Our production managers have navigated the minefield that is music licensing and in many cases were able to obtain favorable permissions for clients.
