 how will be the call, when

    ns_register_filter preauth GET /junk myfilter

is registered? when

   myfilter preauth

is called, this would be pretty much comaptible with  the aolserver for 
the simple cases.
this would  as well work with xotcl methods in this case. however, this 
would as well be
the case, when WHY is placed before the passed arguments.

the hyperflexible approach would be to use

   ns_register_filter preauth GET /junk [list myfilter arg1] arg2  arg3

which calls
 
  myfilter arg1 preauth arg1 arg2

which means, cmd as you suggested, appending optional arguments. this means

   ns_register_filter preauth GET /junk myfilter  arg2  arg3

will make perfectly nice xotcl argumnt lists. In the simple case, this 
ist still
comaptible with aolserver, in the complex cases, one has to do rewrite 
the code anyhow.
