Twitter API support for an academic research


we are an academic research team working on the development of a model to analyze the use of social media (especially twitter) by universities to promote their activities and to advertise. In order to test our model we would like to know whether the software that we are developing within our research can access twitter data and statistics that are more than the limits imposed by the API. Our software will not use that API rule change indefinetely and only for a number of accounts (max. 100) until our research is finalized (July 2013 max). In case the API rules/limits can not be modified for us, is there a way that official Twitter can provide us with the data that we require?
Thank you in advance
