Interesting, but does this have to be centralized? Why can't all of
my devices 'find' each other and then decide amongst themselves
which versions are most current?

(Oh yeah, that would be P2P, and that's been declared dead. Never mind).

Given that I work on a desktop machine for a week here at home and
then spend a week at a time on the road, I can definitely see the
need for this. I use CVS, but that's not a very consumer friendly

And to do this right, I would like to sync up bookmarks, favorites,
installed applications, menu layouts, and more.

People now have available to them a diversity of digital
storage devices, including palmtops, cell phone address
books, laptops, desktop computers and web-based services.
Unfortunately, as the number of personal data repositories
increases, so does the management problem of ensuring that
the most up-to-date version of any document is available to
the user on the storage device he is currently using. We
introduce the Roma personal metadata service to make it
easier to locate current file versions and ensure their availability
across different repositories. This centralized service
stores information about each of a userís files, such
as name, location, timestamp and keywords, on behalf of
mobility-aware applications. Separating out these metadata
from the data respositories makes it practical to keep
the metadata store on a highly available, portable device.
In this paper we describe the design requirements, architecture
and current prototype implementation of Roma.
