By ignoring, I meant in regard to the hiper interface. I use libcurl
in some Windows applications myself, so I know full well you haven't
ignored the OS.

I'm glad we can agree on something :)

And I'd not expect you or anyone to put in that much effort. All I'm
asking is that you make hiper apps portable and efficient on all the
popular operating systems without the user having to write any sockets
code. I'm happy to contribute code for Win2k+ and I'm sure people who
use the less popular operating systems will be willing to contribute
code in the future.

I think this will be tricky to do. I look forward to your ideas!
