Hi,
Reading this thread again, I feel like clarifying a few points.

I think it should be very easy to build and test the LV2 host stack on Android
once the Glib dependency is gone. And anyone can try this since the Android SDK
and emulator are freely available. Plus, the Android NDK

Sure; it is straightforward to define new LV2 port types.

No, but you are talking about getting developers to interoperate. The
Android app model is very segregating so if you want to share libraries
then you will also have to have all developers of each codestream to
share the same signing ce

The apps should still work with float as they would on any platform.
LV2 nor LADSPA are going to add much overhead as they do not
manipulate floats.

It can be a factor of 1000 if the binaries are built assuming there is an FPU.
What happens is you get a system call for every failed float operation. If the

I'm not qualified to answer that. Although, something like the HTTP Accepts
