I'm working for a small IT company, and have been working with  
m0n0wall lately as a possible replacement to some routers we're  
currently using.

The only major issue right now is the fact that captive portal  
doesn't feed back as much accounting information as we'd like (IP  
address, MAC address, etc), and it also doesn't send interim updates  
with bandwidth usage.  Our users will be remaining logged in for long  
periods of time, so interim updates are the current way of handling  
their daily bandwidth usage reports & such.

Searching through the lists, it looks like there has been some  
progress on this front - I've seen references to patches that add the  
requested RADIUS accounting info, but I haven't found anything that  
appears to be discussing interim update support.  It also appears  
that bandwidth tracking on a per-IP basis is in need of some work.

I would be interested in finding out the current state of the captive  
portal/RADIUS development, and talking with someone about the work  
required to get these features functioning.
