Python modules
Three Python modules have been written for pydap and released separetely, since they're quite useful on their own. The first module is arrayterator, a buffered iterator for reading big arrays. This module is used in the netCDF, GrADS/GRIB and Matlab plugins for serving huge files without consuming too much memory.
The second module, coards, converts between a given COARDS time specification and a Python datetime object. It's useful for converting between the string 3439481 jiffies since 1978-03-09 01:30:00 -3:00 to something much more useful.
Pupynere, my PUre PYthon NEtcf REader, is a replacement for Scientific.IO.NetCDF and pynetcdf used by the netCDF plugin. The module implements a netCDF reader in pure Python, avoiding the dependency on the netCDF libraries.
An additional offpsring of pydap is simpleQL, a pythonic interface to SQL databases. This module builds the SQL query directly from Python code, in a similar way to how the pydap client filters Sequences. It was written as an example of how the technique works for people not familiar with the DAP.
