Please note that there are now versions of WinBoard and XBoard available that are greatly enhanced for ICS play, like FICS (freechess.org). For instance, they now support a seek graph, and a simple way to keep tabs on your partner's game in bughouse. For lightning fans, there is also a smart-move option available.
For an overview of all new features, see

The seek-graph of XBoard, that you summon up by clicking the board
while you are not playing, when the option -sg has enabled it.
