Re: [Chicken-users] Idea feedback

[Elf]

quick question, which may be a really stupid question cause im not sure
im understanding properly...

why not do one of the following:
   a) simple string-encoded sexprs to the mobile client, some kind of
      well-formed message to the server? (ie, different format based on
      communication direction, playing to both sides strong points)
   b) define a simple DS message format or lang and use this?
   c) pass around xml?
