yes... that's what i understood.

that should be possible with jackrabbit 1.5.0 already.
despite the fact that it is still work in progress...

ACLs can only be assigned to Nodes. Similarly a Session
holds a set of Privileges on a given Node (and never on
a Property). this is defined by the JSR 283 access control.

however, you still may have finer grained permissions
even for individual properties or nodes:

quote from the specification:
In repositories that do support access control management, the 
permissions encompass the restrictions imposed by privileges, but also 
include any additional policy-internal refinements with effects too 
fine-grained to be exposed through privilege discovery. A common cases 
may be to provide finer-grained access restrictions to individual 
properties or child nodes of the node to which the policy applies.

for this purpose jackrabbit defines refined ACL/ACE
interfaces that allow to pass additional restrictions
when creating an ACE. which restrictions are understood
and/or respected is left to the implementation.

you may take a look at

it is still sort of a draft but you will get the idea.

hope that helps
