Ok, looks like a job for RRDtool.

Most of us can, but it is not possible with MRTG.

That's not exactly what happens.  MRTG takes a sample, then 30 seconds 
later it takes another sample.  And so on.  Doesn't do much until it gets to 
the five minute mark, then does its magic.

Perminute just averages your connections per minute instead of per five minutes.

Not with MRTG.  Use RRDtool.
