Carbon DSP Plug-Ins Question

[Tweakhead]

This move to a new compact design of audio interface with an ethernet connection looks like it could be the beginning of an interesting new phase. Especially the potential for expansion of the plug-in choices actually encoded for AAX-DSP.

Several manufacturers have always been pretty good at this, particularly McDSP. Are there any others coming down the pipe ? Or perhaps some older ones getting back into the partner game, such as Waves ?

I thought that one of the problems with the AAX DSP chip architecture was that no plugins could span processor chips, so it limited the size of code for plug-ins to run on Avid's proprietary chips. I thought that was why Waves and others gave up on writing Avid-compatible DSP, as plugins became more complex, and demanding. Is that right ?
Does the Carbon Interface DSP have newer, larger-capacity processor chips, or are they exactly the same as those on the HDX processor PCIe cards, but simply in a new networkable box ?
