From Maarten and Kristjan Gulbrandsen:

Here is the patch with the restructured PROOF code. It parameterizes
PROOF startup, currently implementing "Standard", Condor, MLM and PEAC.
It can easily be extended with other "TProof" classes, e.g. AliEn Proof.
Or what ever next Grid implementation or scheduler comes along.

The MLM, Multi Level Master, code uses a basic packetizer, based on a
MSD (massstorage domain) tag. In MLM mode we have multi-tier client
server setup, like:

client -> super master -> sub master 0 -> slave[0..N]
                          ...
                       -> sub master M -> slave[0..N]

It also contains a large number of smaller fixes. Credit for most of
the work goes to Kris!

We have tested this on multipe platforms (RH7.3, RH9, SL3) and in
multiple configurations. Should be stable.
