You can, actually, without any external scripts:

ip sla 1
   http get http://mirror.internode.on.net/pub/test/1meg.test cache disable
   tag Internode Mirror HTTP download speed
   frequency 600

Then poll the output result with SNMP (rttMonLatestRttOperCompletionTime.1) -
and it'll give you the time taken for the file to download (+ plug it into
Cacti/MRTG and plot it etc)
