BackJack Continuum
Synectics Business Solutions today announced its public beta of BackJack Continuum, its offsite backup companion for Time Machine. Continuum requires Leopard, and a computer capable of running it. When Time Machine completes its various hourly, daily, and weekly backups, Continuum then synchronizes the backup with SBS' secure servers. Should a problem occur, all that is required is for Continuum to be installed on the system, and the software automatically recovers user data from the secured server. BackJack Continuum is expected to be available in mid-December, and while pricing has not been finalized, the company expects it to be around 25¢ per gigabyte.

if mozy.com fixes their client to be more stable, you'd could pay $4.95.month for whatever that computer backed up and send it offsite to their servers as well.
