Just had a friend mention a start-up named Birdie Wireless out of HK:

Looks like they are taking the Thai telecoms' multi-country concept and adapting it to a wider, self-serve online refill model. I'm going to try it when I'm in HK next week. I'll also be in MY/SG/ID/JP/US/FR so I'll give it a workout. I've never seen a HK reseller with such a wide scope on one card before.
It's available on klook.com.
