The solution to your whiteboard woes: don't use dry-erase markers. Use washable crayons (as sold for small children). You'll never be surprised by an empty marker again. They take a damp cloth to wipe off, but they wipe off completely, regardless of how long they've been on the board.

My experience is they don't wash as well as dry-erase markers.

Propbably the best approach is just to carry two sets of dry-erase markers everywhere, one always sealed.
