The files in the histlogs directory are only used when you drill down
and view the detailed status from sometime in the past. Just to view the
history page (with the overview of when it changed to red/green/blue...)
only requires the files in the data/hist/ directory.

So no - I haven't though much about changing the way it's stored. What I 
currently do is to archive old histlogs/ files one month at a time -
simply doing "cd .../histlogs; find . -name "*_Apr_*_2005" | cpio ..."

I have thought about changing the directory structure so it would be
easier to split the histlogs by month - e.g. from

  histlogs/hostname/testname/TIMESTAMP

to

  histlogs/YEAR/MONTH/hostname/testname/TIMESTAMP

which would make it easier to handle. Since BB compatibility 
is no longer an objective in Hobbit, I can do that fairly easily.
