There's no need for a "hybrid" solution, that's what 14all does already.
If I want a specific rrd's file information, I just put a link like so...


Understand?  It's pretty easy to do, and you can also add &png=whatever and you'll only get the specific time period (daily, weekly, monthly, yearly) 
- you can also add your own if you'd like.  I added one called "last12" and made it graph the last 12 hours worth of 5 minute samples.  Makes it very easy 
for my Network Control Center to see in detail what's happening with 
a link.

This has nothing to do with Perl, more to do with how you design your own MRTG website.
