Thanks for your reply.

I had forgotten about the 2gb limit. That definitely affects program
design. To think I was only concerned with it outgrowing a single hard
drive. :)

This will require further thought.

I knew the DC folks were at LinuxExpo, so I wasn't worried about a delayed
reply. I imagined they are pretty swamped now, considering the well
deserved response. :)

Thanks again.
