Read the counter from the DB, decrease it by the value you want and put 
it into the rrd. Take care that you increase the decrease factor (sounds 
funny) with every cycle. Don't you know about perl?

There is no, you will just have one if you decrease the counters that 
you put into your rrd and not use the real ones. When you get back to 
inserting the real ones there will be a big difference between your 
virtual and the real one. Ugh, is that understandable?
