this code lets you add/delete/modify the sources as a list of lambda functions that call various functions to process the received data. since various sources can be rather slow and i wanted to use many of those in my list i decided to run multiple queries in parallel. so it uses multiprocessing. it requires python2 for now, since python3 removed urllib2.
