Passing data into the PHP Bric Burner

I'm trying to decide the best way to pass data into a PHP template.   
The two major options are:

1) Stick them in either _GET, _POST or what have you
2) Create our own new auto-global _BRIC (or something else) and stick  
things there.

I'm really leaning to #2, so much so that I can't really justify  
considering 1.

I guess my question is, does anyone have any other ideas, or not buy  
idea 2?
