[nflug] speed imaging netcat

[Bradley A. Llewellyn]

If you want to be able to watch the progress, you can get fancy with 
"pv" and "dialog".  I used this to transfer an Innotek VirtualBox disk 
drive to a file server:

(pv vpc1.vdi -n | gzip -c1 | netcat fileserver 1234) 2>&1 | dialog 
--gauge "Transferring file..." 7 70

The key is the "-n" on the pv command.  It outputs a percentage to 
"standard error" (handle '2'), then you redirect '2' to '1' and pipes it 
through "dialog".  "7 70" is just the dimensions of the dialog box.
