That was about the ability to specify an input final state for them, and 
has been implemented on trunk for a bit now. So no (known) blocker from 
that side.

* I would like to do something similar in MC_{W,Z,H,WW,ZZ,PHOTON,}JETS, 
namely split each into at least three different parts:
  - Properties of the hard object (let's call it e.g. MC_W)
  - Properties of anti-kt (0.4?) jets to have a more reasonable 
validation analysis for LHC purposes (e.g. MC_W_JETS)
  - Differential kt jet resolutions since they are so useful for MC 
development (e.g. MC_W_JETRESOLUTIONS)

One comment: I'd very much like to get our manual (arXiv:1003.0694) 
published in e.g. CPC as soon as possible. Initially we were planning to 
wait for a final stable API, but I think we have given up the plans to 
have everything completely stable and final at least for 2.0, so there 
is no real reason to wait for that, is there? The publication of the 
manual would of course not mean that we won't update the arXiv version 
anymore.
If there is support for it, I'd volunteer to take the lead on this and 
do the boilerplate and organisational work, and then delegate to you all 
for specific parts of it.

What do you think?

Cheers,
Frank
