Well, alright, I also do my share of coding, but I'm a sysadmin first.

Assuming that it goes high enough, power disturbation. It's enough of a savings that every decade or so people talk about using current generation superconductors for it, need for cryogenic cooling and all.

Then making a lot of stuff that uses current superconductors cheaper, like MRI machines and particle accelerators.

Sure, I bet that there will be _plenty_ of new stuff, but I'm less convinced that anyone is going to be able to predict what that will be all that well.

Will the general public be able to buy the units? A lot of interesting low cost hardware has come about (like the OLPC), but it's been rare that people off the street have been able to buy them.

Even if there is a very explicit lack of support, it would be nice to just be able to buy them without having to be a school or having an order for 5000 of them.

When the weather changes, the leaves turn different pretty colors, and everything actually behaves like it's fall.

That's when fall starts.
(Date based methods are silly, especially these days.)

At least in the past, most ISPs will only block port 25 for non-business users. And most ISP level blocks are against the consumer DHCP ranges.

So spend the extra money on business accounts with static addresses, and take up the port blocking with your account manager if it's still an issue.

Barring that, spend $20 a month or so on a hosted VM somewhere, and run your mail through that. (Securely, please.)
