Re: [Netmod-ver-dt] [netmod] NETMOD 106 Schedule and Call for Presentations

[Lou Berger <[e-mail]>]

Hi,

We discussed this today.  Our preference would be for a thin/minimal 
draft covering the tooling and the output showing the intended direction 
for the work and for this to be included in the set adoption call.  It 
really doesn't have to be complete /much -- just enough to show intended 
direction.  Hopefully this is minimal enough effort for it to be 
submitted quite rapidly.

Does that work for you?

Thanks,

Lou (Joel and Kent)
