I've checked in my FASTA splitting, which now seems to be
working OK with my BLAST tests. So far this only does splitting
into chunks of the requested number of sequences, rather than
the option to split the whole file into a given number of pieces.

I also need to look at merging multiple BLAST XML outputs, but
this is looking promising.
