  I've long maintained that LDPC is a good choice for flud, based on
some initial experiments that I did a long time ago, confirming that
the *average* number of blocks needed for decode could be made to be
reasonable, even for a small number of blocks.  And while that is
still true, especially when there are a very large number of blocks,
I've done some more recent measurements that seem to show the
*variance* in the number of blocks might be unacceptable (that will
come as no surprise to many).  As part of fixing this, I may have to
recant my previous biases against RS encoding, which *can* provide us
with hard limits on the number of blocks needed.
