Tess,

That pretty much *is* the web-service API I was referring to. The  
only difference is that I suggested that a successful response should  
be a redirect to the "secondlife:" URI described in the original  
announcement. That allows the normal HTTP response codes to do the  
rest of the job.

That's covered in the response codes. HTTP is designed for this  
situation.

Successful login:
     303 Success-message-for-user
     Location: secondlife:...
     Other-headers...

     -- no body ---

Authentication failure:
     403 Failure-message-for-user
     Headers...

     HTML error message

Server failure:
     5xx Message-for-user
     Headers...

     HTML error message

Special handling:
     307 Message-for-user
     Location: URL requesting more information
     Other-headers...

     --- no body ---

The viewer doesn't require any new complex code. No matter what the  
response is, it contains a message to display to the user. If a web  
page display is required, it contains a redirect to that page. The  
client can display that in llMozLib or redirect to an external  
browser. It can even use the existing framework for llLoadURL to give  
the user a dialog approving that redirect.
