Dear Kris, Jonathan, Robert,

Thanks for all your valuable comments.
Comments from industries are really appreciated, as i always asked
whenever i presented the documents.
I'm now quite tied-up by other meeting in Argentina,
so i will update the document applying the comments as soon as I
return back (next friday).

I also appreciate Daniel, Carl, Kihyong, Jungsoo, Hamid, Saif, and
other 6lowpaners who sent the support.

Thanks,
-eunah
