Sounds good, but it raises some additional questions:

1. It looks like I would need to set up an external RADIUS server. 
Looking at the "apt" repository for Debian/unstable, I can see several
different implementations to choose from:
  a. freeradius
  b. radius-cistron
  c. radius-livingston
  d. xtradius
  e. yardradius
Does anyone have experience with any of these RADIUS servers?  Any
recommendations?  Recommended literature?

2. What do I need to do to make a client box running Debian/unstable
support the RADIUS protocol?

3. The router is capable of using either TKIP or AES; exactly the two
protocols you recommended.  Are there any advantages or disadvantages to
using one rather than the other?

To err is human, to forgive is against company policy.
