Hi Glen-
Sven's done great work, and people should take advantage of his library,
if they're using Swarm. 

My point, which others have also said, is simply that you don't *need* to
use something like Sven's library, or Drone, or random.org, or lava lamps,
to get "good" seeds. As Knuth says, any legal seed is fine, as long as you
don't reuse a seed within a set of runs.

The only reasons I can think of why you might *need* to use a more
sophisticated method to choose seeds are if you're doing cryptography, and
(perhaps) if it's required to prove the validity of a statistical test
for your data.
