Just for your information.

I ran across this paper on implementing Reed Soloman Algorithm for 
Parity Volumes. This is the way that most split file error correction is 
done in large usenet postings. RAR something and then generate a series 
of PAR files.
If it is similar or the same as what Freenet uses for FEC then the paper 
might prove a valuable resource for people working to create an 
efficient implementation.
If it an alternate method, it might be useful to make Freenet FEC 
extensible enough to incorporate this in the future if automated tools 
come out making inserting these things into usenet easy (and perhaps a 
future usenet/freenet gateway that you can connect to with your 
favourite newsreader).

Here is the link:

and the spec for PAR files:
