I was wondering if anyone knows of a commercial application or preferably an
open source project that operates similar to the way users gain access to a
broadband hotel internet connection.

General description listed below:
A network level application that manages access to your network. It prevents
rogue computers from connecting to your network and gaining access to network
resources. By restricting what computers can obtain a valid network IP
Address, a network administrator has a low maintenance tool for managing
access. A new user plugging into a SecureDHCP network will be assigned a
"Special", non-routable IP address that will only allow them access to the
SecureDHCP web site. This customizable web site can require a new user to,
for example, fill out a form identifying themselves, acknowledge the reading
of an "Acceptable Use Policy" document or download and install current virus
software. The system will then replace their "Special" IP address with a
valid network address that provides full access. Hardware addresses as well
as user data are saved in a database for reporting and troubleshooting
purposes.

Anyone know of an open source project that seeks to meet this kind of need?
Any information would be appreciated.

Not that I know; but your requests isn't taking into account some
(imho) important issues:

what if the machine is (e.g.) a Mac or a Linux based one ? Are
you saying you'll deny network access to such machines just
because the "AV" software or whatever else won't work on
them ?

I think a simpler solution would be using managed switches
and setting up VLANs this way you may configure each switch
port as a separate VLAN and setup the VLAN so that they'll only
be able to see certain "servers" (e.g. the internet gateway and so
on) at this point you may (for example) install on the internet gateway
a filtering software to deny access to certain sites/subnets and/or to
remove any "dangerous" traffic (worms and so on); such a thing will
work independently from the O/S or the H/W used by the client

Take a look at NoCatAuth (http://nocat.net) - it does what you're asking
for.
There are commercial packages - MetaIP from Checkpoint is one that comes to
mind, there must be something from Cisco and whole heap of others.

Also try Googling for "active portal".
<http://wiki.personaltelco.net/index.cgi/PortalSoftware> looks like a
good resource.

Good luck finding a free one for Windows, though.
