HTTP is probably the best for doing file transfers. If you do want to
transfer files with PB, use twisted.spread.util.Pager. See StringPager
for an example. It's trivial to convert this to a FilePager.

If you really do want to change the size limit for banana, you can do it
per-process (patches to properly parameterize this accepted) by changing
banana.SIZE_LIMIT.
