I presume that this will also reduce the amount of network traffic
that it sends. When I tested it from home a few days ago using a
dial-up connection, it was using 100% of the available bandwidth.

I presume it is doing a non-blocking read then? Should be
easy to convert to using select() with a timeout (which will
also give you your millisecond 'capable' timer).

If you point me at the code, I'll have a look.

Again, if you want I'll take a look.

Go for it, as long as we remember to point out that it has
a different licence from the main source.

I can't see us writing additional code specifically for web
support, especially if we can use someone else's code to do
it for us.
