Technically, the answer should be yes. I think you can run any chunk  
of binary code linked against static libraries. Code signing can be  
taken care of by the codesign command-line tool and you can drag  
properly signed apps into iTunes for installation onto the iPhone.

Tethered (on the iPhone) debugging would not be possible without  
reverse-engineering the usbmuxd protocol, unless you manage to use gdb  
to debug Ruby code.
