Aaron, i read your spec. One comment to your last statement:

> 1<http://bazaar-vcs.org/HistoryHorizon#fnref-7d8a63d0abc9cc0190e944b3efde75930de92b9b-0>Some time ago I heared GCC CVS repository is something like 800MB, so it's
not so much out of question


I just checked our corporate CVS server for some numbers:

  - number of projects / modules: 194
  - diskspace usage for the modules: 45 GB
  - largest project size: 5.5 GB
  - average size of the 10 most important projects: ~2 GB each

Two of our offices are connected to our server with a 4MB line only (i know
that a lot of private
households have faster connections). So yes, it is not out of question ;-)

Even when not working in a distributed team, a history horizon would make a
lot of sense.


Ciao,
  Steffen
