will rsync use the delta-copy (rsync algorithm: portion of the file that has changes) with a regular NAS, or is a rsync server required.

To use rsync directly you would need to be able to run it on the NAS unit as well as the local station.  There are some NAS that do have rsync built in.

It can be used to copy from a local system to shared drive mounted on the local system though I suspect this will negate much of the benefit of the delta copying on bandwidth usage.

All the ReadyNAS line from Infrant (now apparently owned by NetGear) support Rsync,

Synology uses rsync for its backup,  not sure if you can rsync a workstation to thier NAS but you can rsync from thier NAS to another rsync enabled server (including to another Synology NAS).  This leads me to believe that it would be possible to rsync any client to thier NAS with the right settings.

Thecus have 'Nsync' backup package with thier NAS units.  I would guess that this is likely something similar but of thier brand.

There is a chance that any linux based NAS that is more business oriented would support rsync or some customized version.

To be honest though this is an example of why I suggest just setting up a linux server.  It does depends on the scale of system but for mid range situations the cost is typically similar or even less than a appliance NAS.  So you get the added bonus of full control over the configuration for both software and hardware.
