Yes that's right, but the CODA solution does not seems to be the best. My own
tests :
- cp -r /etc/* /coda
That's about 16 Megs of files and it took more than 3 minutes to complete
with a venus cache of over 40 megs ... Awfully slow ... (tested with coda
5.3.8)
CODA is really not ready for production purposes !
Beside this point, the technology is REALLY great ...
