One Router, One Switch, 2 PIX's

What issues arise if I have a router which plugs in to a switch (2950) and I have two separate PIXs attached to the same switch? I have a block of Public IP's (6 usable), 5 would go to PIX1 and 1 will go to PIX2. Am I looking at a routing nightmare? Both PIXs are 506's...and will have separate LAN networks attached.

do you have one internal network? vlans or subnets?

We have a business partner that we want to remove from one side of the network and want to put them on their own PIX. No VLANs, PIX1 is company side, PIX2 would be business partner side. If both PIXs are connected to the switch (residing before the router), will I have a routing issue given that 1 IP will go to the interface of PIX2, while the other IP addresses reside on PIX1?

The switch will build the MAC tables indicating where each PIX device is located (on each respective port) for each PIX attached to the switch.

The route statements from the router simply "route" the packets destined for the that network out the designated router port. ARP request is answered and the packets are then sent to the correct PIX.
