>Conversely, competitors like JoinMe (which is part of LogMeIn) use a Flash-based viewer, which won’t work on many smartphones (including, famously, any iOS devices)...

It requires Java so I still can't use it from my phone (not that I would expect to be able to show anything outside my web browser anyways).

The java screen share isn't limited to showing your browser, it'll show your entire monitor. And this code is different from joinme in that it doesn't require flash to view someone else's monitor, its viewer works with JavaScript.

It only requires Java on one side.
