The examples write to a file, but they don't seek, so you can write to a 
network stream as well.

Take a look at oggfwd or exstream for examples:

  http://v2v.cc/~j/ffmpeg2theora/oggfwd/

Or the libshout library, if you're writing your own application:

The reference encoder is floating point, so performance is often an 
issue on embedded devices.

Hope that helps,
