When I talk about Radio and my love/hate with it, this is one of the things I absolutely positively adore, fawn over, and plan to mimic in as many of my projects as I can where I can. Back when the Mozilla source code was first released, and I happened to be at a Q&A with some Netscape guys, this was the #1 feature I pestered them to spend time looking into.
John Robb of UserLand points it out, in relation to .NET:
[Alchin said, "]The hot patching technology will not find its way into the upcoming .Net Server family, but we have made progress on reducing reboots.["]Yes, yes it does, and this is dead sexy. I love that the system is put together in such a way that this is possible. My monitoring of the Radio.root Updates RSS feed reminds me daily of where my $40/year is going.
Radio already does this.
Now, can we have Instant Outlines do this? :) Heehee.shortname=oooabf
