I'm hoping to try installing this on a shared site-shared database webhost (1&1).

My webhost allows me to have multiple websites by serving from different subfolders of the root and I have a number of sites including several WordPress sites running concurrently but they all share a single database; each site just prefixes the table names with a unique prefix.

Is it possible to install i-doit in this way? I've checked the problems and questions others have raised while installing and one problem I can foresee is that i-doit seems to want to create a dedicated database; it doesn't allow the same trick that wordpress facilitates?
