Why aren't there more integrated courses around?

Heres an interesting one for discussion, given that, for achieving an FATPL taking an integrated course is by far the best option (if price were not an issue), with less hoops to jump through that the Mod route, why are they only offered by so few FTOs?

I would imagine that there are a set of CAA/ JAR criteria which must be satisfied by an FTO in order to offer the integrated course, it would be interesting to know what they are.

Given that the likes of Stapleford and other highly regarded mod schools would appear to have similar standards of training/ aircraft etc to the likes of OAT, the only thing that springs to mind is that an integrated provider must have to provide its own on site ATPL ground school, which the modular FTOs do not appear to have the capacity to do.
However, given that the ground school is taken right at the start of an integrated course, why shouldnt it be possible to do the theory elsewhere, and then integrate the remaining flying side of the training into one package?

Or are there a more deeper set of criteria which must be fulilled?
Given the gravy train that the likes of OAT are on with their integrated courses, id imagine that many mod schools would jump at the chance to offer integrated training, so why don't they?
