IIRC there have been talks about this on this list, years ago, but  
the idea was abandoned because of the complexity of the matter:  
unlike their LaTeX counterparts \( and \), the $s of plain TeX do not  
have left and right forms, which means a number of particular cases  
must be considered when moving forwards or backwards in a file so as  
to catch the matching $ for a given $. It might even, I imagine,  
involve parsing the whole input file.

That said, I think Emacs and/or Alpha implement syntax-coloring of  
formulas between $s, which means they must have some mechanism for  
detecting matching $s. (Don't swear by it, though, as it's a very  
vague recollection and I may as well be completely wrong.)
