Convolutional Reverb + DSP module

Hi, anyone knows about any project that uses the Juce DSP module to implement a convolutive reverb? One that goes a little beyond the demo that Juce provides.
I need to make a VST plug-in of a convolutional reverb, which is capable of charging IR of 4 sec. or less (I read comments that it was not possible with Juce, only up to 1 sec).
Any information you can give me to begin with would be helpful.
