I think it's a nice idea to rename into Bengalooru. Though it's a place belongs to Karnataka, the population of Kannadigas is approximately less than 50%. Also, most of the Kannadigas who work in IT and BT fields speak in English. So, inorder to give a flavour to the name and to bangalore, it's a good idea. The name may look odd for some time, but once it is adopted, then there will not be a problem. The people from outside Karnataka also should learn the Kannada language little-bit, so that they can mingle with the common man and slowly Kannadiga.
