The network configuration you described is called a Wireless Repeater
Bridge.
While IPCop might be able to handle the networking requirements (I'm
not sure if IPCop can be a wireless repeater bridge or not), it is not
designed (nor is it desirable for a firewall) to provide file/print
services.
I think easiest solution for this would be to use DD-WRT. It can be
configured as a repeater bridge (see
http://www.dd-wrt.com/wiki/index.php/Repeater_Bridge), and DD-WRT can be
run on a wide variety of wireless devices.
While it might be possible to add samba to DD-WRT in some instances (see
http://www.dd-wrt.com/wiki/index.php/Samba), I would recommend against
it. Filesystem access would be at USB2 speeds, and I don't believe this
would provide printer sharing. Samba on DD-WRT is not a pretty picture.
To provide file/print services, it would be simplest to build a
standalone samba server for file/print sharing. This server could be as
little as an old PentiumII machine with 256M of RAM (more ram would only
increase file caching). I would recommend building this on a raid-1
(mirrored) array. If more than 2G of storage is needed, you can use raid-10.
BL, let DD-WRT handle the networking requirements on a small wireless
router device, and build a separate server host (attached to the DD-WRT
device via ethernet) for file/print services. Remember to KISS. ;)
This sounds like an interesting project. Have fun with it!
