Kern,
I am confused by your statement:
"
Yes, I am working on this now (a very low priority project for the
moment) but it will probably only be in the Enterprise version and not
in the community version."
Are you looking to start having features only in the paid for version?
I thought that all versions would have access to the same code, this is
from your web site:
"
There will be no separate “enterprise version” of the Bacula source
code. www.bacula.org will continue to be the home for Bacula project
development."
Thanks -Jason
