Good way to send/receive UDP packets?

[Dukc]

I have a project where I need to take and send UDP packets over 
the Internet. Only raw UDP - my application uses packets 
directly, with their starting `[0x5a, packet.length.to!ubyte]` 
included. And only communication with a single address, no need 
to communicate with multiple clients concurrently.

I understand that I could do it either with the Curl library 
bundled with Phobos, or use Vibe.D or Hunt instead. But it's the 
first time I'm dealing with low-level networking like this, and 
my knowledge about it is lacking. So seek opinions about what 
library I should use, and more importantly, why.

Other advice about projects like this is also welcome, should 
anyone wish to share it.
