It would be good to support service provision at the script level --  
allow a script to be called when an info.plist-specified service is  
requested from the app.  On the consumer end, some sort of selection  
modification would be a good long-term goal, but most services are  
not of this type, but more along the lines of "open XX in YY", or  
"new window with selection", etc. that only need the clipboard to be  
sent.  If I get some time I'll try to propose something more specific.

Multi-keystroke input methods (e.g. for Chinese characters) work in  
Tk under Windows currently, so maybe the raw vs. processed issue for  
bindings could be handled the same way as there.  Implementation- 
wise, an NSView can implement the NSTextInput protocol and have  
access to both the raw keys and the characters composed by whatever  
system input manager is active.  (The Cocoa port of emacs does this.)
