Er... not sure whether there is any web proxy running in your system.
A cheap and maybe easy way (depending on expertise) is to have a
transparent web proxy via squid.  Squid has a URL rewrite feature.
Just rewrite any URL request from wireless network to a script written
by you and this script will do a pop up and redirect the user back to
the URL he/she is intended to.

Additional benefit: URL logging by squid.  Properly you want to
monitor network usage by visitor more closely.  Further more, you can
see the user id and password when the vistor tried to do some
plaintext web login.

How can I have a pop-up open each time a user opens a web browser to
warn of
misuse?  We installed a physically separate wireless network from our
internal network just for visitors to have internet access, and would
like a
warning to pop up each time they open a web browser with show our
Corporate
speal about misuse and they would have to acknowledge it with the
click of a
button before being allowed access.  We were thinking about something
like
Microsoft ISA 200 Server, but would prefer something that's easier to
implement and cheaper.  Let me know your thoughts.
