> I still say networked audio belongs in jack, not a plugin.

It belongs in both:

 - If you want to use the network to increase your total processing
   power, you probably just want to offload some plugins to a remote
   machine. Sure, you may run jack-rack remotely and send/receive
   the data through a jack client locally, but this may become a
   mess in some situations if you need the plugin to be run "inside"
   an app. It also prevents you from using any kind of plugin
   automation. Therefore, is such cases it is more interesting to
   use ladspa for the distributed processing.

 - OTOH, if you need something more complicated to be done remotely
   (like disk I/O or running a complete instance of ardour), using
   jack (as both me and Steve Harris described in other messages)
   may be better.

VST System Links works on top of ASIO, not VST. Don't know about
FX-Teleport.

It is a hack, but a useful one.

And why is that a problem? You just load a special plugin that appears
to be the plugin you intended. The app can't tell the difference.

In my system, everything is completely transparent to the app.

See ya,
Nelson
