Hmm, i think i'm misssing something here. What i want to do
is the following: I have written some daemon that acts as 
a middle tire to query search engines like glimpse. The front-
end opens a socket to the server and sends a query. The server
translates the query to the backend query format, queries the
backend, caches the reply and sends an answer to the frontend.
Frontend/server communication is done with a http-ish protocol.
I've written Java/Perl and Python modules/classes for the proto-
col part and they seem to work fine. Of course i could do some-
thing like:

 <dtml-in expr="query(server="192.168.2.12" port="7777"  query="bla")">
   .....
 </dtml-in>

but since the people who have to maintain the site are basically
non-technical i would love to have a less error-prone alternaive
syntax bycreating my 'own' dtml tags. From what i understand so
far dtml-methods are stored fragments of dtml code. I don't see
how i can accomplish what i want with dtml methods.
