    BLCR developers,

We are developing process migration support for Host Identity Protocol 
[1] to our Linux 2.6 kernel implementation of it [2]. The process 
migration itself is not our focus, but the communication aspects 
related to migration are. Therefore, I'm checking the status of 
different process migration implementations for vanilla Linux kernel.

We intend to integrate our HIP based TCP/UDP communication migration 
support to the chosen migration implementation. Moreover, the migration 
implementation should support migration of network server applications 
consisting of multiple processes (communicating via shared memory/IPC). 
Therefore, I wonder what is the current status of the following planned 
items on your web page:
- #  Special device files such as /dev/null, /dev/zero and /dev/random
- # Coherent checkpoints of process groups and sessions
     * Process group support allows checkpointing of command pipelines 
(e.g. grep foo bar | sort)
     * Sessions support eases integration with most batch systems and 
allows checkpointing of login shells
- # Support for Linux 2.6
