Knoppix + tar + bzip2 + netcat, but beware... it is REALLY FAST :).
On slower lines (up to 100Mbit/s incl.), the line will be the bottleneck (98% avg. usage),
on faster ones (we tested on 1Gbit/s fiber optics ethernet and 2GBit/s Fiber
Channel) the ATA disks used on the client were the limiting
factor :).

on client/source: 
$tar c / | bzip2 -9 | nc server port

on server:
nc -l port | bunzip2 | tar x

Please note, that netcat has also UDP option. Using it this way
leads to having lost of fun... ;-)))).

Netcat is also available on Windows under CygWin. With Knoppix
able to mount NTFS read-only, this has some interesting-to-explore
implications... :).

Have a nice day...
