Yup. I'll fix this. Thanks.

No, you can put them in the same module, as in:

  [data.py]
  import ZODB.FileStorage
  Dados=ZODB.FileStorage.FileStorage(
  '/usr/local/zope/Zope-2.2.2-linux2-x86-server/var/Data.fs'
  )
  News=ZODB.FileStorage.FileStorage(
  '/usr/local/zope/Zope-2.2.2-linux2-x86-server/var/News.fs',
  read_only=1)


  $./start_zeo -SDados=./data:Dados -SNews=./data:News

Note that there was a bug in ZEO 0.2.3 (and earlier).
This was fixed in 0.4.0.

I'm not sure what you are trying to say here.
