Jon,

I understand your concern too, and personaly i would like to add
that i have a positive opinion on TIPC .

I think the technical clustering options have to be debated more in detail
before external announcement.

Eric

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).

Regards /Jon
