Here's an interesting solution to a problem you may not have known you had. How to share the moments of your life, live, with others. Knocking Live Video is a free video-sharing app for iPhone, and now for Android, that broadcasts live video from one smartphone to another.

There's nothing new about live streaming video on these platforms or others. Qik is a free service that similarly broadcasts live video from smartphones and feature phones to the internet. However, Qik can be public or private , whereas Knocking Live Video is currently only private, and Qik streams to the Internet. Knocking Live Video's niche is phone-to-phone broadcasting, which is inherently a private way to share when both parties have Knocking Live Video up and running on their phones.

Knocking Live Video debuted for iPhones in December, after a little misunderstanding that the cofounder's personal e-mail to Steve Jobs helped straighten out.

The addition of an Android app doesn't add new functionality per se, but it does make it possible for far more people to take part in what is a handy system of sharing the moment live. We won't lie--the private aspect of one-to-one streaming appeals to us. Even so, we'd like the option to broadcast to more than one other buddy if we choose, and there's a host of other features that could make further use of the video, like transcripts and taking still shots with a soft key for a start.

Still, Knocking Live Video is one communications app we'll be keeping an eye on, particularly when it finds its way onto even more mobile platforms, like BlackBerry and Symbian smartphones and Java feature phones.
