For some reason this only works for localhost, but not for other addresses. This is not very useful...
I'll need to dig into what's going on here.

For some reason this only works for localhost, but not for other addresses. This is not very useful... I'll need to dig into what's going on here.

After some more debugging, here's what's going on:

wasip1.DialUDP("udp", "127.0.0.1:1234", "8.8.8.8:1234")

fails, whereas

wasip1.DialUDP("udp", "0.0.0.0:1234", "8.8.8.8:1234")

succeeds.

I think this makes sense, since 8.8.8.8 is actually not available on the lo interface. You need to send from a different interface.
