WoW guys & gals, im overwhelmed with the response to this, thank you all very much.
Some of your ideas I have considdered, like a diode to the B0 pin, but I dont think that would work for my app, I need to have as many pins as input as possible which i think is about 33 at most on the 18f4550 (and 2 pins could fire at the same time), I will take a closer look at some of your suggestions on my day off work, it looks like some of it involves assembler which I dont get :-(, but Im sure I will pick something out of your ideas :-), Im just wondering if just polling the pins would be fast enough @ 20mhz, I'm gonna give all your ideas a try this w/end and see what works, thx
