You can download and run BLAST locally to save network traffic, if you
prefer, especially if you have many queries to run. Binaries are available
for many platforms at http://www.ncbi.nlm.nih.gov/BLAST/. Of course, you
need space to store the databases. For example, the non-redundant protein
sequence database is a few hundred MB I think...
Parsing BLAST XML output (using the option '-m 7' when running BLAST from
the command line) can be done easily using the NCBIXML module in Biopython.
This method has the feature that you have a static BLAST version and
database, so allows for reproducibility, which can be viewed as an
advantage or disadvantage, depending what you want to do.
