Wireless syncing: Photos and public wifi networks

Hi--
I have two wifi-syncing applications I haven't figured out yet: photos and public wifi networks.

Has anyone been able to sync their photos (preferably into Aperture) via wifi?

Has anyone been able to do a wifi sync while connected to a network outside their own wifi network (like a library's, or Starbucks' network?)

Replies will be appreciated, no matter how simple the solution ;)
