My script will tell you how long a particular hydrogen bond persists, in terms 
of the percentage of time occupied in a given trajectory.  Likely what I 
suggested was to use the same logic to parse an hbmap.xpm file to determine when 
hydrogen bonds existed simultaneously between different proteins and a common 
water molecule.  One could, in theory, expand the script I wrote to do this.

Having never had a need to make such modifications, I cannot provide much more 
insight, but I know it is possible.
