That is possible, but I wouldn't consider VideoLAN as the best fit application for this right now (although some people are working on that)

That's possible indeed.

If you're  unicasting, the only  thing that might  block you would  be a
firewall. Event that could be avoided, using HTTP as a transport instead
of UDP.

MPEG 4 should give good results, provided you computer is fast enough to
encode the stream.

Although there are some cyphering  / decyphering functionalities in VLC,
this is not a "out of the box"  feature, and I connot see an easy way to
implement it here (I might be wrong on this).

Although, I  could be  required to  play a bit  with different  access /
access out  buffers (in  the preference window),  to reduce  caching and
delay.
