I don't think we have a problem here. It's simply up to the server to 
handle this. Basically there are two approaches:

A: Flexible command to uri mapping, defined by server and resolved by 
introspection:

<commands>
   <checkout>/hello/world.html?action=neutroncheckout</checkout>
</commands>

The server is responsible to reserve some of it's uri-namespace 
(including request params) for neutron requests.


B: Static commands:

Consider neutron a xml-rpc webservice and keep all (hardwired) commands 
in the request body of POST.

/hello/world.html?action=checkout ==> /neutron/
POST
<cmd>checkout</cmd>
<resource>/hello/world.xml</resource>

Here again the server is to reserve some of it's uri-namespace for the 
service endpoint - usually a single uri per service. In the case of 
Lenya that's a bit hard to implement I know - no excuse for not 
considering it anyway.

In both cases there's no use for WWW-Authenticate anyway.
