Hi Ron,

the thing is that the ESP does not know anything of the bundles sent. 
I think the better way would be to set the delta to a negative value 
and catch this in NetAddr. However this would normally be an overhead 
for everyone else. One way couls be to use the message 
schedBundleArrayOnClock and check for a negative value there, adding 
to a dictionary on the server (hm, one more thing the server takes 
care of). Perhaps really it is time for a smarter NetAddr.
