Someone once wrote about a UDP library, which was used to sync 
data to somewhere in APAC (Hongkong?) and by doing so the data 
transfer was magnitudes faster then before (over TCP)...

I couldn't find this info now, neither in the forum not something 
meaningful in code.dlang.org...

Maybe the author is still around or someone else has this post at 
hand and could share it?!

Beside this, there is:

Hope this helps...
