The best recent data I have is from Bangalore to Tyco Road in  
Virginia through VSNL and Cogent.

Here is a sample (this goes through San Jose) :

Mon Mar  5 05:26:21 EST 2007
from Bangalore through the VSNL network
--- 63.105.122.1 ping statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max/stddev = 285.495/319.649/395.330/38.576 ms

370 ms seems a little high but not unreasonable.
