My onjly issue with the above/below is the using oif the SplitFile prefix,
when they don't behave anything like standard splitfiles. But someone
else mentioned this point and actually made arguments, iirc

I assume this is the equivalent to my stream.type=live/stream.type=static
metadata, non?

Why not in blocks?

Well, the format should actully be a standard mime type, imho.
One important thing to add, which I havn't implented in my stuff because
I'm sticking to ogg audio for the moment, is a header key, which points to
a key containing the header data for this file - to stream asf, for
example, you need to first prepend a generic ASF header to the stream.

How *I* implented FEC functionality, is added metadata stream.fecn=x,
stream.feck=y, and then had each block as SSK@key/stream/block/splitblock.
Before anyone asks, no you *can't* have a single metakey that contains
your FEC splitblocks for each block - what happens if you can't retrieve
that key? effective redundancy is then zero :).
Freenet seems to be improving, btw - it's now keeping 75% of the keys from
fishland, which is up from 50% a few weeks ago. I probably should look at
all of this again and see if the network is up to handling it again.
- fish
p.s. yeah, i know that I should have replied to this 5 days ago - i went
away for a few days, and didn't catch up on my old email until today.
