Web based Chart software讨论

I trade at work and i use NETDANIA's charts toplan my trades on. The problem however is that when i go home my trading plan would be stuck at work. It would be great if there were a cloud based charting software that marries up with the system you have in place at the moment. This means i can plan my trade and manage it anywhere due to it being in the cloud. If there are people using this type of service please let me know. I am not talking about VPS either, i need a strictly JAVA based platform.
