I've been running a similar setup for a few months, feeding data to http://www.flightradar24.com/ http://www.flightradar24.com/. If you upload data to them like this then you get premium access to their site and app which is nice. In fact I found that using the site was easier than accessing my own data on the pi so I haven't really used planeplotter etc. I found that I can pick up a lot of planes even with the stubby antenna that came with the DVB stick. But I'm pretty close to the Heathrow flight path which gives me a slight advantage! The dump1090 process uses 30-40% CPU on my pi so I start it up with nice -n+19. And it does seem to crash quite often so I've got something to check and restart it.
