Pydap is an implementation of the Opendap/DODS protocol, written from scratch. You can use Pydap to access scientific data on the internet without having to download it; instead, you work with special array and iterable objects that download data on-the-fly as necessary, saving bandwidth and time. The module also comes with a robust-but-lightweight Opendap server, implemented as a WSGI application. WWW: https://pypi.python.org/pypi/Pydap
