The problem is rendering "faster than realtime", rendering "slower than 
realtime" is perfectly possible, I do it often.

Rendering faster than realtime isn't quite as simple as upsampling, you 
have to scale all clocks to match (like [metro], [delay], etc). 
Shouldn't be too difficult to hack Pd to work properly in this 
situation, as long as everything timing-centric adds events to the 
scheduler through the same mechanism.
