Symbol for the Indian Rupee

Symbol for Indian Rupee
106. In the ensuing year, we intend to formalise a symbol for the Indian Rupee, which reflects and captures the Indian ethos and culture. With this, Indian Rupee will join the select club of currencies such as the US Dollar, British Pound Sterling, Euro and Japanese Yen that have a clear distinguishing identity. — From Indian Finance Minister Pranab Mukherjee's 2010-11 budget speech to Parliament

Interesting to think what it will be. How soon will it show up in font sets? and so on.
