The ID in and of itself is not a bad thing. However, there needs to be a full and thorough discussion of the issues such as privacy, duplication, theft etc.
From what I can see, this scheme seems similar to SSN's in the US, and using them as an example, you can easily see how the aforementioned issues can come into play.
IMO, there needs to be a rigorous debate in the media about this scheme and also a detailed explanation from the government on how they plan to address these concerns.
Knowing what Indian Media is like I would rather not want this to be debated. Given Nilekani is heading it and the fact that the government is actively working to bring in any relevant person or advise I would assume they would do a good job of analysis the pros and cons and the feasibility of it in a country like India.
Things have to start - we cannot keep debating. I understand revising or doing it again is costly in India. But whatever the current investment into this pays of in just one use of this - ensuring the facilities are not misused. I bet there is more money people are shelling out in bribes as a whole to misuse than what is required to prevent it. One investment of govt I would not complain about even if I have to pay a nominal fee for it or raise funds.
