But I really dont care what protocol is chosen I only have a couple
requests/suggestions

  In Search Results Send an extra integer defining clients inet speed so
the info dosnt need to be
  retrieved from the server userlist(although this result isnt necicarly
true at least it will save some
  cpu while parsing).

Perhaps we should take the problem from a different point of view: is a user list really necessary ? Most of the time, we will "private-chat" with either someone we have received a search reply from or someone we already knows. A command like "$IsOnline nickname[,nickname...]|" is probably better (moreover, the hub can notify a client when the user with the given nickname enters).

  Also in search results I think a Feild should be set aside for fileinfo ie movie dimentions or music
  bitrate and time.

It looks good but these informations are meaningless (quality of non-lossless format mainly depends on the quality of the initial source), fairly hard to obtain (you must process all shared files) and will create clients which are unable to be maintained because there is dozens of file type and new ones are regularly available.
