pysco is not likely a good candiate. its ideally suited for algorithmic code, 
but more importantly for particular functions, as its memory use grows rather 
quickly the more lines of code it needs to cover. i don't think binding it to 
zpt would be feasible.

the other options are optimizing the alt-tal/zpt implementation, or writing 
zpt/tal in C (which i've heard rumors that shane has done in his spare time).

or maybe just using dtml :-)
