Has anyone applied for this recently?
What kind of emergencies are considered acceptable?

Also, it says that your travel date must be within next 72 hrs. (i.e. 3 days).
However, what about cases where travel date is more than 72 hrs. but not enough time to get Indian visa by mail?

How long is it taking these days for adult Indian visa for people of Indian original (i.e. with previous Indian passport)?
Is it between 1 to 2 weeks?
If so, what should one do if the travel date is more than 72 hrs. but less than 2 weeks?

My travel date is exactly a week away and I don't know whether to go for emergency visa or send passport.

You better take emergency visa. You have to pay extra bucks for the service.

Thanks, I would indeed like to use the service.
But will they give me emergency visa?
The website says medical or humanitarian emergency only.
I don't have either, just a general travel emergency.
Do you or anyone else know what all is acceptable as emergency?

Thanks
