I've got perl scripts that do this.  I'd be happy to donate them to 
the archive if you're interested.

Yes, this works well for getting info into the emulator.  

However, I was not able to use this method to get info out of the 
emulator.  In particular when I first got the emulator I wanted to 
examine all the files on the rl0 disk using the much nicer work 
environment provided by Linux.  Having tar write to rl1 fails 
around the 1.4 Meg mark (anyone know why?), whereas I was able to 
dump the entire contents of the rl disk to a simtape with no problem.

Here's what happened when I tried to dump the entire rl0 disk:

Ed

sim> att rl1 junk.dsk
RL: creating new file
sim> cont

# pwd
/
# tar cvf /dev/rrl1 *
tar:    p: cannot open file
