[cgl_discussion] ANNOUNCE: OSDL Clusters (foundational components)

[Jon Maloy]

Neither was it ever discussed why OSDL *must* go out with their own
version of TIPC, despite numerous invitations from Ericsson to cooperate
about the project.
We may now be in the unfortunate situation that we will have one OSDL-
version of TIPC, 95% based on the Ericsson version, occupying symbol space
in Linux kernel, and  which we, Ericsson, the originator of the concept and
code, can not use.  This apart from the fact that we seem to  have no 
influence
on the further development of the code, -all my suggestions for retaining a
minimum level of portability and usefulness for ourselves  have been 
manifestly
ignored.
- And another version, very similar, still maintained by Ericsson, and 
likely
to be part of different distros by 2004.

Maybe it is time for OSDL to start considering cooperaton here, instead 
of competing
with our own customers (and sponsors).
