i2c performance and waveform generation

Hello - I'd like to use an i2c DAC to generate a 1000 samples/sec waveform in C++ or Java. Couple of questions

  1. Is I2C fully supported in Up Board under latest ubilinux 4.0?
  2. Is I2C fully supported in Up Board under MRAA library in C++ and/or Java?
  3. Is it possible to generate ~1000 samples/sec, low jitter performance using Ubilinux / Up via I2C to stream waveforms, using MRAA code or another library? Concerned about real time performance of ubilinux.

Any experience or links to code would be appreciated!
