Hi Marek:<div>According to Lang's suggestion, I think DH and DSS is a better choice. Thanks for your generous. DH and DSS is strange to me. I need to to learn more about this. I accept it 's difficult for me to absorb your proposal . it's better for me to get this step by step. As i said in my gsoc</div>
<div>proposal I'm interested in this. joining the wine project is the best for me. </div><div><br></div><div>thank you.</div><div><br></div><br><div class="gmail_quote">2013/5/10 Marek Chmiel <span dir="ltr"><<a href="mailto:kcmark@gmail.com" target="_blank">kcmark@gmail.com</a>></span><br>

I have yet to touch anything with DH_EPHEM (Ephemeral) or DH_SF (Store and Forward). If you have any questions shoot them to Juan or me (Juan is the better choice). Best of luck!</div>
