No - the last phoneme of the previous word alters to harmonise with the first 
phoneme of the following word.  My understanding was that he wants to know 
how to handle this final consonant harmony.

The problem is that it applies across a word-boundary.  It's actually similar 
to Celtic mutation, but that has been handled within the word, even though 
the trigger for it is also across a word-boundary.  I assume you mean 
something similar to that for the analysis side.  For English-->Tamil, I 
woudl try approaching it by having the ending specified as -eX, and then a 
post-generation shaping rule that changes X to the first letter of the 
following word.
