From what I understand, IP Anycast can be used to steer traffic into a
server that's close to the client.
I am curious if anyone here has/encountered a setup where they use
anycast IP on their gateways... to have a predictable egress IP for
their traffic, regardless of where they are located?
For example, a search engine crawler could in principle have the same
IP advertised all over the world, but it looks like they don't... I
wonder why?

Its definitely possible, but would need a layer of software (kernel
mode) on all the anycast holders synchronizing state to ensure
asymmetric replies/connections get forwarded/shifted to the correct host.
If the goals are worth that kind of effort is another question. And
performance is likely to be "tricky".
