I want to create a file on another system (at home for example), bring 
it into work, put it into my teams folder and have the ability for the 
rest of my team (group) to be able to read and write to it and "others" 
to be able to read it.

I have a Tech and Finance folder.  I want each file underneath that 
folder to be owned by the group a certain group. To keep it simple, the 
'tech' group I want to have rw access to the Tech folder recursively as 
well the Finance folder, the 'finance' group will have rw access 
recursively. I think I got this down with setguid +s.

So for instance... I want all the files in a certain folder to look like 
this:

-rw-rw-r--+  1 andy.graybeal      tech          0 2010-09-14 16:32 hansolo

andy.graybeal at buddleia:/srv/Desktop/Tech$ getfacl hansolo
# file: hansolo
# owner: andy.graybeal
# group: tech
user::rw-
group::rwx			#effective:rw-
mask::rw-
other::r--

andy.graybeal at buddleia:/srv/Desktop/Tech$

So.. if someone takes a file home and works on it and brings it back, I 
think it loses it's permissions, as well as if someone creates a file on 
their system at home and brings it in to work.

I hope that makes better sense.

Thank you for asking a clarifying question.
