First, this discussion belongs on the LV2 mailing list. :-) In fact,
we've been discussing it recently. See [1]

Second, the current intention is to send an Event with a URL to load a
sample file (whether the event comes from a UI or another plugin or
whatever). In order to accomplish this, a standard event type has to be
created. That's what the "Atom extension"[2] -- it's like a standard
library of event types.

HOWEVER, stepping back a little bit, in you could create your own
private event type and send it over an Event port.

[2] There's talk of renaming it the Atom extension to something
     like "Variant" so that it's easier to understand.
