My startup is really similar. We also value people over profits (and we're profitable!), we all work remotely, and we all meetup in random places for a few weeks so we can get a vacation plus some face-to-face working time in.
So far, it's been awesome. We've only done 1 meetup so far, at a ski chalet in the Alps, and it was great. The significant others & kids came for 1 week, and then we had 2 weeks of just the employees.
The biggest challenge is definitely the internet. When you have 6 people in a house all trying to pull/push from git, sync dropbox, do skype calls, etc; it can put quite a burden on whatever crappy DSL the vacation house has installed.
We would love to do a SE Asia work trip but so far we have ignored the region due to the internet connectivity. I'm actually really surprised that the mobile internet there was good enough for you guys to work with.
Cheers, and keep it up! It's nice to see there are more startups like this out there.
