Renewal of B2 visitor visa for another 10 years for my mom in US

[geminiabode]

Dear Sir / Madam,

My mom has 10 year visitor visa B2 which expires next year in June 2013.
Right now she visiting me in US and will be going back on November 2012
She has never overstayed in the past 10 years and does not intend to do so in future.
She does not need a visa extension.
But I do want to eventually renew her visa for another 10 years.
Is it possible to do that while she is in the US ? (This is not to extend her stay but just to get the visa renewed for another period of 10 years)
If its possible what are the steps ? can I do it all by myself here in US?
Or is it advisable for her to do it in India upon her return ?
She might be eligible for visa waiver. (She is 70 years old now)
In case she has to do it India what are the documents she need to submit to the consulate?

Thanks a lot in advance for your reply.

Firstly, she and not you, will aply for her B-2 visa renewal.
Secondly, it has to processed at an overseas US consulate. The same type of documents that were needed for her first visa application will be needed for her renewal application.
