You may use http://redeem.bitwatch.co/ and remove the dust value limitations via the settings tab to catch non-dust transactions as well (e.g. min. amount: 0, max. amount: 9999999). I build it to help meta-coin users to reclaim multisig output dust, but it should be possible to locate other unspent outputs as well.
More information and alternatives were mentioned in a similar thread:

Topic: How can I get a list of UTXO keys? (Read 1978 times)
I am wondering if someone is working on this. If we have a list of bitcoin address / public key would this method give us the list of UTXO ?
You didn't say you wanted the entire unspent transaction output set 
There is no way that I know of to do this from the command line / JSON-RPC, although that information is in your local database. You could write your own JSON-RPC handler to do it.

Um.
I can't find any way to use 'listunspent' to get more than just the utxo's associated with a particular wallet or account.
I want a list of all the unspent txouts in the entire blockchain.
Am I missing something, or do I just need to write a blockchain explorer to get my list?

thank you. 
listunspent
Is there a handy way to use the RPC interface (or something) to extract a list of the transactions (including pubkeys) associated with unspent txouts? Some special command on blockchain.org? Something? I know the client has to build and keep this list handy; I'm just wondering if there's a way to look at it.
