Maybe I should be more clear to avoid confusion. Whether subsequent
opens of the same file fails or succeeds depends on the parameters
passed to those open requests. There are rules of how the open params
of an existing open interacts with params of incoming open requests
but they are not as restrictive as you've mentioned. Long story short,
it's quite possible to open the same file multiple times for writing.

in relation to each other, that's all controlled by the applications
and nothing is enforced by OS, file system, or CIFS/NFS servers.

I can also access and change the files on my ubuntu machines. This is
all working well, except that Id also like to be able to write files
from the OpenSolaris machine. Do you think its wise to have everyone
using one account? It seems like there might be some issues that
might arise if two people open the same file. Generally as I
understand it, if two users open the same file, the first person who
opened it has write access and the second person has merely read
access. Is this the same with one account? Or should I just create
several accounts that have global access.
