GMail Backup on Local Computer

I just suggested a new feature to GMail:

Offer a way to download all messages older than x days to a local computer and make them searchable (i.e. using Google Desktop Search).

This would be a way to clean up disk space while keeping older e-mails. 1 GB is smaller than we may think!

And another one (March 29th):

Include a download-feature so I can burn my old e-mails on CDROM.

If you want that feature too, please let Google know!
