Hello Scott,
I did indeed extended TCPServerSOContainerGroup and this works fine for me,
no problem there. I was only wondering if more people could use the
functionality of dynamically adding groups to a server. Of course, if you
want to add this functionality, you should do it according to the ECF
architecture.
thx,
Guy

Hi Guy,
It might very well be a good idea to expose a 'container group'
api...especially since we are planning work on ECF servers as an
important sub-project of ECF...i.e.
http://wiki.eclipse.org/index.php/Eclipse_Communication_Fram ework_Project
(will be working on this over next weeks...*please* if people have
comments relevant to 'ECF for servers' or other project plans then
communicate them publicly...i..e on this newsgroup or to
ecf-dev@eclipse.org OR file an enhancement bug report at
http://bugs.eclipse.org (under ECF project of course).
Thanks Guy. I might want to engage you in further discussion and design
about server APIs (e.g. container group)...and maybe even get you to
contribute further.
