 Tristan,

 You are just repeating my question !!! LOL -- this was exactly what I said
when 
I first tried to work with the proprietary, close source/info, software.--- I
asked their company?
 
 Did you guys know that there is something called socket and that would make
your app network transparent ?

  Answer: Oh, it is esasier for our users to access the protocol through a flat
file.

   I said: "Well, now every user running on a dist. environment needs to set a
socket server of their own on a machine just to do what your software could do
in the first place -- Now we have to write a server, a file locking mechanism
that on windows correctly ( We initially used JAVA to write to this file, but
stupid, brain dead JAVA did not have file locking -- and now it does not work
properly on 1.4 -- end side note). { try : file.getChannel.lcok(), and you will
get a ugly exception!!).
 
  Are you sure you guys still think that it would be easier ??

  Then I said -- people make stupid mistakes -- they just have a tough time
admitting it.

  Sorry for being so humble :P)


 Is that funny or what ? ( I hope you had a good laugh :P)

Harring.
