DESIGN-Q Very good potential esp. if this is kept as a donation-ware. Among its feature, it can connect automatically to an open network (with option to only connect if quality/strength is past user-defined level and/or if not already connected), growl support, MAC address capture, favourites and past history with graphs.
Very easy to use, well, even if it only scans at a regular interval (can only do this when the main appl. is running though). In short, a good addition to other appl/widget you might already have on your portables.
