user8764: Is there any wallet client that conforms to the following:

The wallet client is accessed through a website (for portability).
The wallet client does not store any private keys (I know there is some trust involve). I want to access coins by providing a private key only, not by creating an account on the website.
Most importantly, all the transaction change is to be payed to the original address. I do not want any additional addresses created during a transaction. I want to keep it as idiot-proof as possible and not rely on myself to keep track of any additional addresses.

Thanks

user8701: If you don't want the client to generate any private keys for you, it seems what you need is a javascript client that builds and propogates transactions.

This is a hosted javascript client (everything happens on the client side so there is no security concerns) allows you to provide a private key and build a transaction that way.
