You should be able to set (almost) any type of data you want.  I just
tried with ints, lists, and dicts and did not get an exception.  Could
you send more info?

Sure, anyone connected to the shared app can set data.  There is
currently no lock mechanism built into the shared app structure.

Currently, no error is raised.  The file will be overwritten.
The venue client handles this by checking for the presence of the file 
before
the upload, and prompting the user to overwrite it if it exists.  Your 
shared application could do something similar.
