This sounds like a fairly standard setup.

I have done similar migrations in the past and it has been fairly 
straightforward. We provide a utility called "buildsql" in the distribution 
that you may find useful (you can modify the source if you need to).

There are no problems with multilink.

There are a few things that Tacacs can do that Radius cannot. Specifically 
logging of command lines entered on the NAS, as this requires a TCP 
connection (Tacacs) rather than UDP (Radius).

We have a great many customers using this combination with excellent results.

We provide some indicative performance numbers in section 24 of the Radiator 
2.19 reference manual (included in the distribution in the file 
"doc/ref.html").

There are also some descriptions of real customer installations on the web 
site (http://www.open.com.au/radiator/examples.html).
