Using 'computer' is a bit disingenuous there. Upgrading a computer sounds like you're buying a new laptop or replacing hardware to deal with a software protocol change.

The software installed on my computer doesn't understand your new record type, so if you want me to see your site, you're going to have to wait until I upgrade it.

I have a hunch you upgrade at least once every six months or so, often to music (;

My point was that your wording made it should much more like a hardware upgrade, which is on a slower cycle for sure.

And I think you'd probably good. I hear your preferred OS has a good track record for implementing new networking stuff quickly.

Well, yeah, but more generally there are other people too. :)
