[kepler-dev] File Activity Simulation: Please suggest

[subhav mital]

Hi Norbert,
This is just a case of Collaborative Sharing. Either some application, or
for eg: A Shell Script modifies the contents of the file.

So once the Script executes something and changes are made to the file, then
the copy back to the Client needs to be triggered.

I am not clear how will this be automated, but maybe a poll on the remote
server to check if the file is received, and to check when updating is done,
to copy it back.

Can you think of something similar?

Also, another questions I had. Can the execute, cause some changes to the
copied file on the remote server?

Thanks a lot!!
