[clug-talk] File permissions: add but not modify/delete?

I have a directory that I want group 'x' to be able to write to, but not
modify/delete existing files (yes, that would include files they just added).
I'm no expert, but as far as I can tell standard *nix permissions don't have
the flexibility to provide this functionality. Please correct me if I'm
If not, then I'm looking at using ACLs am I not? In that case, I believe I
need the following (again, please correct me if I'm wrong):
1) A filesystem which supports ACLs
-I currently have ext3 and ReiserFS v3 filesystems
2) A kernel w/ ACL support for the given filesystem
-just a recompile away ;-)
3) Userspace programs to modify ACLs
-separate download or included in ext3/ReiserFS v3?
Now, my question would be, can I use an existing ext3 or ReiserFS v3
filesystem or do I need to reformat w/ a "--use-ACLs" type argument? Or can
I just recompile my kernel w/ ACL support and use included userspace tools?
Thanks for your insights,
