Nobody suggested hacking "seqret" to do what you want...

One problem doing this in EMBOSS is the need to generate filenames for your 
  split files - but maybe a base filename would be enough to generate 
names. Then all you need to do is count sequences in a modified seqret.c 
and change the output file. You can add a command line option for the 
number of sequences in an output file. Cleaning up output files for a rerun 
is an exercise for the user (unless you want to invent a new ACD type that 
does it :-)

Needs a modified version of the seqFileReopen function to handle the file 
naming, but nothing complicated is involved.
