You can use the webif to do it but you'll have to open the HTTP port (and transcoding port, if your upload speed is poor) in your router in order to do it.
I'd recommend changing these ports in your receiver first , changing the default receiver password and also enabling HTTP authentication (need password in order to stream)
Otherwise you may find someone else hijacking your webif/streams etc and once in, it's the same as handing them your remote, or worse!
Access your webif plugin (normally green button) and the rest is self explanitory.
Then you'll have to open port/ports on your router.
There is also an app for your phone VU+ player (in the app store, dunno about android though)

Master G got there first..
