title: RIA vs. RCP
body: <p>I'm on a project where we try to build a GUI replacement for an old application. Before we really implement the functionality we've started prototyping with Eclipse RCP (Rich Client Platform) and GWT (Google widget toolkit, a Rich Internet Application). What is your experience with RIA and RCP GUIs? When does it make sense to use RIA and in which situations a rich client is more suitable? With the current possibilities of RIA, it becomes more and more difficult to draw the line.. Do you have any experiences?</p>

  <p>EDIT: 
  All your answers are really interesting. I'd like to accept all of them as they contribute to the answer of my, I admit a quite open question. So my vote up for each of them. Hope the bounty will be shared among you.</p>
