A full and thorough reading of this proposal will reveal that the VoA is actually applied for on-line, in advance, and paid for then too. Any queues will simply be to produce "biometric proof" of ID and collect visa.
As far as queueing for a long time John, I see you have only been to Goa once before, maybe you were lucky? Same at any other Indian airport, long queues are commonplace, especially at busy arrival times, such as a Russian Jumbo arriving just before!
As to "saving a few bob", the present cost for a UK citizen for the shortest T visa comes to well over £100 with postage, despite being applied for on-line. I think most on this forum are hoping to save considerably more than a few bob!
The current Indian official view on introduction varies between October 2014 to the end of the year ("hopefully", their words not mine!). Add to this the fact that everything in India happens late, and final;ly a general election in a few months time. Personally, I very much doubt if there will be any progress next season.
