There's an extension to tcpd which I've seen floating around which does this.
There's the FSF inetd (which floats around the net somewhere) which is not
that much bigger than the standard inetd, which also does this. I'm using it.
I'll have to dig out the sources and post it to sunsite, someday...
Delayed connection acceptance would be just great, but (as Alan (I think)
mentioned when I brought that one up last time) it causes problems with
the originating TCP's round-trip-time discovery algorithm. Too bad. :-(
