The way around API limitations on how much data can be read is to resort to scraping. However, Twitter probably blocks individual IPs that access too much data.

The way around API limitations on how much data can be read is to resort to scraping. However, Twitter probably blocks individual IPs that access too much data. The solution to that is to convince enough users to install software that lets you access their website - preferably via forwarded SSL so your users can't compromise data integrity. Users get some reward, presumably quite small, for relaying the requests for you. The scheme could be opened to provide unofficial paid APIs for Twitter and other 'walled gardens' that make data available to unauthenticated users on the Internet.
