I just upgraded [OmniOutliner for iOS](http://click.linksynergy.com/fs-bin/stat?id=r*bqlTuiXSo&offerid=146261&type=3&subid=0&tmpid=1826&RD_PARM1=http%253A%252F%252Fitunes.apple.com%252Fus%252Fapp%252Fomnioutliner%252Fid430118869%253Fmt%253D8%2526uo%253D4%2526partnerId%253D30)[^fn1] and the [release notes](http://d.kivus.net/BvEA) mention the ability to use Omni Sync Server to download outlines. The [Mac Version](http://click.linksynergy.com/fs-bin/stat?id=r*bqlTuiXSo&offerid=146261&type=3&subid=0&tmpid=1826&RD_PARM1=http%253A%252F%252Fitunes.apple.com%252Fus%252Fapp%252Fomnioutliner-pro%252Fid404647179%253Fmt%253D12%2526uo%253D4%2526partnerId%253D30) does not yet seem to be updated to support Omni Sync Server functionality, but I hope this iOS update is a sign that syncing will be coming to OmniOutliner soon.
