Now, what *exactly* does "simultaneously" mean for you ?? Is there a limit in a specific number of milli or micro seconds that still is regarded as "simultaneously" ? You could add external sample/hold curcuits to "lock" the inputs at a common timestamp and than read them from the PIC. Or use another PIC (PIC24/30/33) that has multiple S/H curcuits built-in.
