Right.

Sorry, I beg to differ. Many plugins these days have I/O and other
requirements approaching and in some cases surpassing the capabilities
and complexities of their host apps. I feel that it's more realistic to
accept and accomodate platform differences rather than trying to implement
some entire "GMPI-POSIX" API that the host or some GMPI library must
implement.
Also, the more this is talked about, the more I am worried about attempts
to divorce the DSP side of the plugin from all the other things with which
a plugin is concerned... you will end up with something like ReWire which,
whilst good at what it does, is not ideal for developing plug-ins from
scratch.
Regards,
Angus.
