Skyfire's mobile Internet browser is quite impressive. After you install the browser client on your Windows mobile phone (and soon for Symbian, iPhone and Blackberry), you'll be able to display "any web site, any web applications and any web video" just like on your PC. So how do they that?
Skyfire is using a client-server architecture. Meaning that most of the protocols, plug-ins, etc... are on the server, with a very compact client on the phone. According to Skyfire's CTO Erik Swenson, the company developed the browser from scratch in C++.
