First off FRR is excellent. I've been looking for something ever since I was blown away by seeing QuickSilver on a friends Mac.
Now, what makes QuickSilver utterly revolutionary is the context system. FFR has added support for the context menu, but it seems it needs to be clicked, thus making the purpose of a super-fast keyboard launcher not so fast or so "keyboard"!
This screenshot shows QuickSilver (QS) at work. The user has found a file, presses <tab> and can now search for contextual tasks to perform on that file. In this case move the file to another folder:

I see two options for development. First is to somehow allow the contents of the windows context menu to be accessible by FRR. This puts the burden of the contextual items at Windows doorstep, FRR just packages those items in a keyboard driven search system as it does already. Does windows make this info available?
Second is to make some hard-coded "actions" and just present that list letting the history and scoring mechanisms of FRR to do the work. This could of course be made more elegant and smart as needed.
Of course the UI to present the contextual items needs to be thought out. I suppose splitting the results window in two panes and letting <tab> select the result pane item then move to the context pane would be fairly trivial to set up using the Windows UI elements. Of course QS has a Zen like elegance all to itself, but as long as functionality is there, the wonderful Zen aesthetics of QS can wait!
