"And if you do, have you written a bundle for it? :-)"

Saw that no body seemed to answer Oscar's question earlier, but I too occasionally use groff, nroff and the mom macros and would love a bundle. 

Currently I have to go to emacs still.   

Mom does come with a syntax sheet for use with elvis, a vim clone which I have included (2.4 kb) if anyone would like to make a quick textmate language file.
