Hmm . . . if you do have ssh in both directions, perhaps you could have
the script reside on the client and have the server call it.  So the
client script would be:

#!/bin/bash
x2goscript ${1}

and the server would be
#!/bin/bash
cp spreadsheet.xls ~/media/someshare/
ssh clientaddress "x2goscript someshare/spreadsheet.xls"

If it can't be driven by the server, then I suppose one could create a
daemon to poll the share directory for the appearance of new files.
Just a couple of thoughts - John
