To create a transparent proxy, you need to nat all traffic normally outgoing on port 80 to your squid.
While the squid proxy can only have one nic without a problem, your nat-router or firewall should have more than one. If you have a managed switch which support vlan tagging (ieee 802.1q) you can add as much virtual interfaces with seperate subnets as you want (or whatever your switch supports, usually enough).

If you can configure your router to transparently proxy the requests received on port 80 to the squid box while any requests seen comming from the proxy server's IP are allowed to pass through, you can.
cisco uses WCCP for this.
If the squid proxy can not be confirmed using the wccp mechanism, the forwarding will be removed and people will have direct access.
