If space is not an issue, you can use split(1) to divide
the input in N pieces and then use a separate loop to copy
them to the media. If you want to stream the distribution
on stdin but still copy to N disks or whatever, you can
write a simple C program that will prompt the user to switch
media, print out checksum etc. If you want to *not* split
files across media (and no file is greater than media size),
you can use makekit from Rich Salz's cshar (comp.sources.unix
Volume 15).
