Nicholas Harbour, who at the time was working for the Department of Defense Computer Forensics Lab (DCFL)

wrote a loving modified dd that writes to multiple files and streams to multiple programs at the same time. The program, dcfldd, also introduces the sorely missed VERIFY operation, and even block-by-block hashes, ( dcfldd Man page)

Maybe someone will combine this with dd_rescue, ddrescue and dd_rhelp to make the ultimate "Convert and Copy" utility :-)

Ah and I can dream of SCTP support too :-)
