I'm using the above for a project, seems to work fine for my purposes. 
Although you have to get a hang for working around some of the xenstore
watch oddities/limitations (firing once after setup, firing on child changes
without you knowing what actually changed because you don't have the previous 
value, but most of the things can be worked around using the watch 
token. I use a pickled dict of the watched path and the current value as the 
token at that seems to work).
