I really like this feature for continuous value functions like bandwidth
utilisation, but it can be annoying when measuring values which are by
nature discrete (for example, people in a room, or number of users logged

I'd rather know that "at approximately 14:45 there were exactly 20 users
logged on", than "at exactly 14:45 there were about 20.534 users logged on".
This is particularly confusing when it is only possible for a maximum of 20
users to log on at one time!

I've even considered adding a new, un-interpolated type (an ABSOLUTEGAUGE
perhaps??) to rrd.  What do you think?
