What is the feasibility on putting block chain on Google App Engine? I would like to do this since my app relies on Google App Engine. I just want to read out of the block chain.
You could probably copy it up there and write yourself something similar to blockexplorer, I believe the source for it or something similar is out there.
Another solution would be to use the RPC-interface to bitcoind and place the blockchain + bitcoin somewhere else, for instance - EC2 (which have a free tier first year for a micro server)
This is what I have did for the litecoin faucet
