While I hear a lot of negative comments here, then I am actually doing what he is asking, crazy huh?
We have a set of applications that require low latency to India and does not take much bandwidth - only servers in India can give us the low latency of <100ms. Currently our setup is based on a set of business ADSL lines, each at 1Mbit/s up/down, from two different ADSL providers. We have 1) three SUN X4140 servers at our office, one running Linux which handles multiplexing the ADSL connections and two running our application in a failover setup; 2) an APC UPS together with a Honda generator for power-safety. We use DNS SRV in the protocol to handle balancing and when one provider is temporarily down. It HAS happened a few times that both providers have been down at the same time, luckily not more than our SLA can handle up to now.
The setup works very well, but, as I have been asking in another thread here on the forum, we are thinking to move to a datacenter, to have more flexible bandwidth management. But, we need a datacenter which is within few hours of travel from our office (Nellore), in case of some hardware problem with the servers.
I agree what others are saying: I would only recommend this kind of setup if you have a business case that can pay for it, a service that does not require traffic bursts (web-pages are usually a service that require traffic bursts), and a SLA (or users) that allows for some downtime. I think 9000INR/month is expensive for only 2Mbit/s (up/down?), even in India
