But they are not are they, they are completely different providers, the
poster was saying how they wanted to address completely different
service providers using JIDs similar to:
+48123456789 at sms.chrome.pl/vodafone
+48123456789 at sms.chrome.pl/orange
But personally I dont think that is the right way to go about it,
resources IMO should really be used for addressing the same entity just
how they are used in c2s terms, and IMO different service providers are
different entities. The other way is to do as Pedro suggested and use:
+48123456789 at sms.chrome.pl
and just allow the one gateway to route the text message via the
cheapest route itself.

So you are suggesting when addressing transports we use JIDs similar to
12345 at gw.xxxx.com/msn
12345 at gw.xxxx.com/yahoo
12345 at gw.xxxx.com/aim

Migration is a completely separate issue to the addressing of the
gateways, that just needs a protocol so you can easily migrate
automatically without much real effort from the user.

No you dont, if the gateway is not available you will get an error
returned to you and you can just try resending to a different gateway.
