I agree with #1 & #3. But those just move an endpoint between PIDs. That's
fine. At any given time, the endpoint is only in one PID.

But I disagree with #2. The endpoints in a multi-homed network may have two
different routes, but they are in one PID, not two PIDs. Here's how I look
at it: if I want to send a packet to 10.0.0.1, I just tell the network to
send the packet. I do *not* tell the network the route or which gateway to
use. That's the network's job. And the network does its best to hide that
from users. Similarly, an ALTO client just wants the cost from endpoint A to
B. The client doesn't want to guess the best route. That's the ALTO server's
job.

Subject:  Re: [alto] Problem with "longest prefix" rule for mapping
endpoints to PIDs

A few points to consider.

Yes, an endpoint can move from one PID to another in case of Mobile IP

Yes, and endpoint can be found in multiple PIDs if it is in a multi-homed
network, I.e., a network where the gateway is connected to multiple
networks. 

Yes, and endpoint  can move from one PID to another if the Gateway is down
since a host interface can be withdraw and the endpoint will move.

Thanks,

Reinaldo
