Then block it from LSL for now and just give us an external web service. 
  I assume with this new http authentication cookie deal, we could do 
this easier, right?

It's a pretty huge issue, the way we have to do it now is use Curl to 
log in to the actual SL web site, and bang on the balance there.  That 
surely creates more load!
