Soonr or Latr?

Soonr is one of the few new startups that seems to be offering a service that's useful; it lets you access your PC from a mobile phone, and place calls via Skype using the computer. There's only one problem: it's not open source. Make that two: there isn't even a GNU/Linux client. Maybe it'll happen, sooner or later.... (Via TheOpenForce.com.)
