    This is great stuff!

    I have a suggestion... lets say you were digging into the source code
    somewhere and wanted to know whether the same function existed in other
    distributions.

    e.g. so for example when you push into a source file and click on the
    hotlink representing a function, instead of it just telling you who
    references that function within a single distribution it would also
    tell you who references that function, and the location of the function,
    in other distributions.

    e.g.

    Referenced (in 1 files total) in:

	* kern/kern_event.c
	    o line 94
	    o line 108
	    o line 192

    Function also found in:

	* FreeBSD-4.x kern/kern_event.c line blah [hotlink] [diff]
	* FreeBSD-current kern/kern_event.c line blah [hotlink] [diff]

    And, just to be absolutely insane about things, it would be cool to be
    able to diff a function between distributions.  Obviously it wouldn't
    be able to follow the history of a function that got renamed, but it
    would still be very cool.
