What I've been waiting for: ISP redundancy on PIX/ASA

I don't know how long I've wanted this...but by chance searching I found it exists as of the middle of last year:

ISP redundancy/tracking on the Cisco PIX and ASA as of the 7.2(x) release!

You can now use a second, inexpensive ISP (like DSL or cable) as a backup to a primary ISP - it's implemented with "tracking" a downstream IP address with ICMP, and if ICMP fails, the default static route is replaced with a backup.
