AFAIK, a custom GUI in LV2 means either you use the same toolkit
as the host, or the plugin GUI becomes a separate process. The
latter may be fine for one or two plugins, but it doesn't scale.

The dynparam extension and init-time parameters are two separate
things. I don't know if LV2 allows the latter. Maybe with another
extension. 

I may consider writing some of my apps as LV2s if and when there
is host that has all the extensions I need. That is not the case,
and I don't see it happen any time soon.

That is correct.
