New to Java

Hello,

I would like to know if I can I use Java to create a PCAnywhere/Remote desktop type of GUI capture/transmit application, or is that too low level for Java? Should I use C++ for that?

I'd like to create an application that would allow me to open a document or application (.pdf or .chm) on one computer, and then go to another computer and access what I was just working on. One of the reasons I'd like this is because I do most of my work at my desk, but when I want to go have a smoke, I'm using my laptop on the porch. I'd like to go to my laptop and be able to continue what I was doing in my office, then go back to my office and finish what I was doing.

I understand there may be applications out there that do this or something similar to this (if you'd like to suggest any that would be great), but the main reason of asking this is to learn more about the limitations of Java. I'm still too new to Java to really understand it's limitations.

While we're at it, and because it's not really off topic, what type of things can't Java do (other than write device drivers/OS's)? Can you have your Java applications installed as a Service in Windows and as a Daemon in Linux, or is that too OS specific for Java to tackle? How about other OS integration topics, such as creating TaskBar items/menu's? What are the limitations of making Java Apps look/feel/behave like native applications?

Thank you very much for any feedback in advance.
