It sounds to me like you do not have to use 2 lines for handshaking.  This may
be a bit depending on how your communication works between the PICs.  A nice way
of doing it is to use only one line, and use it as active low in the same manner
as I2C.  i.e  when the master is ready to send, it releases this line.  If the
slave is ready to receive, it will also release this line.  When the master
detects this line as high, it can begin transmission.  When the master releases
this line and the slave is not ready to receive, the slave will hold this line
low until it is ready.  If you haven't used I2C before :  This kind of
handshakind is made by connecting these lines directly to each other, and
connecting a pull-up resistor to Vdd.  The line is released by a controller by
setting the appropriate pin as input, and the line is held low by setting the
appropriate pin as output with the value zero.
