Are you planning this features? 1) category tree in frontend 2) localization of goods 3) top seller by category 4) automatic price manager - custumer form EU can use price price with Vat or without tax (if they pay tax) and non-EU customer use price without tax 5) wholesale price
1) category tree in frontend. Yes! But you can do yourself (modify Modules\Navigation\CategoryNavigation.ascx user control). 2) localization of goods. Yes! 3) top seller by category. Yes! 4) automatic price manager. Yes! 5) wholesale price . Yes!
Unfortunately ECB (http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml) doesn't support indian rupee. You should fine another currency live rate provider and modify GetCurrencyLiveRates method of CurrencyManager class.
P.S. I think we'll rewrite it to interface so several currency live rate providers will be supported
