I've been working for some time (solo) on a concept that could manage to alleviate some of your concerns. There are ways around them today (API), but who knows if they'll be foreclosed upon in the future.

Like many old farts, I imagine, I see your post in terms of the thick-client/thin-client battles of years past. I don't think FB will ever see it in their interests to completely close their garden, which would really be remaking the mistakes of the past, but stranger things have happened.
