Hi Bertrand,
there's an SQLite file at the directory "archive" of each demo: index.db

Your question arises again the problem of the lack of a common API in IPOL.
Then, how to retrieve the number of experiments of a given demo? In my  
opinion, this should be done via a webservice that isolates from the  
SQLite operations.

For example, it could be obtained with an URL like, for example  
http://www.ipol.im/webservice/stat?demo=123 and receiving a JSON  
response with all the information about the demo.

In fact, I think that everything should be done that way, splitting  
the demo system into several independent modules.

Therefore, if we want to add this new feature, it's the good time to  
start with the webservices.

Best,
Miguel
