Dear Jonathan,

I have sent off an email to Adobe asking for them to at least consider adding 
the combining diacritics to their OT fonts. I am not holding my breath. I 
even thought of adding them myself, but I suspect this might not be permitted by 
Adobe's licensing policy? Also, I fear there would be unforeseen complications 
with the OT tables that i would not know how to solve. 

I doubt anyone else will be greatly interested but I got my Indic underdots 
to work by using an old macro (not by me) called "diatop". Here is the code 
(the value of \raise.175em is may need adjusting for other fonts, or for heavy 
bold etc.):

     \setbox1=\hbox to1\dimen0{\hss#1\hss}%
     \hbox to1\dimen0{\hss#2\hss}}}
\font\body="Adobe Garamond Pro" at 11pt\body

Here are some underdot characters used in transliteration from Indic scripts: 
\d{r}, \d{d}, \d{t}, \d{s}, \d{m} etc.
