While I haven't tried this yet, it's my understanding that with PIX 7.0 
this is possible to do with the same-security-traffic command.  
According to the PIX documentation 
(http://www.cisco.com/univercd/cc/td/doc/product/multisec/asa_sw/v_70/cref_txt/s.htm#wp2668461)  
this allows you to "permit communication between interfaces with equal 
security levels".
