Thanks, this is really helpful :-).
I think remoteStorage is a great feature, but as with SAFE, there is problem getting it adopted, and I guess the IdieHosts is a recognition that giving users control over where their data is hosted is not going to be easily solved with a handful of new apps when most users are going to want the massive range of apps available on existing hosting. Step one was I guess things like Softaculous, and hopefully IndiHosts can add to this on the migration side.
Much as I like it, I think its difficult to "sell" remoteStorage to app developers or to hosting services. I'm still going to consider adding support for it on SAFE though, so long as it is fairly straightforward - fingers crossed :-). I'm also looking at noBackend and offlineFirst frameworks, as well as CouchApps. My aim is to simplify building web apps, and make it easy for devs to port or write for this new backend. If you know of any others I might consider, please let me know - I'm not very knowledgable here so researching from scratch.
As for your apps, well I might add SAFE support myself . Thanks again for your help.
By the way...
Glad you have heard about SAFE
