[Owncloud] Synchronization in owncloud

[Hasanat Kazmi]

5. Clearing my "service discovery" point: We always have to enter URL of
WebDav host. If we use service discovery mechanism (e.g. like that used in
iTunes, which finds other computers in the network sharing music), then we
can automatically locate the server which is being hosted within the network
-- e.g. if take out my laptop and connect to home network, Now my cloud is
also hosted in my home network and it exposes its host service to the
network. The client on my laptop will find it automatically and tell me that
my last sync was with that host (or there is a new host, do I want to create
a sync relationship with that?).
Secondly, I can also search for hosts/clouds... Do you think this can be a
good feature.. Right now all syncing solutions lack such a functionality.

We go with WebDav. I still have reservations for large file: if we
are transferring a blue-ray movie and connection breaks half-through, so on
reconnection, do we have to start transfer from beginning or can we
implement a download manager sort of functionality to tackle this?

I have a little confusion about what have you envisioned. Should it be
something like, a folder which syncs automatically (like dropbox) or are
you envisioning something more.... please elaborate.
