This is a great tool to use with Android smartphones. I can run wireshark on my phone but all I end up with is a pcap dump file and you can't watch it in real time. There are viewers for Android, but this could make quick uploading and viewing very easy. Going to upload from my phone now to test it out.

Edit: Seems to work really well as viewer for Shark for Android. Although I do agree with the security concerns it's still a very cool product.
