Since it seems the "number has changed" message has expired on the old phone number, you might want to make note of the new address for Silicon Prairie Software (makers of HyperCache Pro):

(We've been here almost two years, but still a lot of mail goes to our old address. So, here's the "new" one)

Silicon Prairie Software
N202-4771 148th Ave NE
Bellevue, WA 98007
(206) 556-0618

email support: hyper@iceonline.com

In response to a few questions of late:

Yes, we are still alive!
Yes, we are still producing and supporting HyperCache.
Yes, it really should be built into the operating system :-)
