Instead of showing the warning message in XI: "Xplico is not running, please run sqlite2_demo.sh...", we could try to start it with this solution:
as it needs to be root, sudo would help us. Summarizing, the idea is giving sudo permissions to the Apache user, but only for running dema, only for that script. I know it sounds "it is not secure", but it seems to be enough safe.
Another option is suphp (http://www.suphp.org/Home.html )
I think this solution is complicatted, but we could have it in consideration for long term, perhaps next months we could study it.
