classic Amigas need XENA?
XENA without official support by XMOS including the development tools is useless, on whatever form
It's possible, it would be interesting to see what uses people could find for it in a classic Amiga.
Audio applications have already been suggested, XENA could give us a 16/24 bit sound card, speech recognition perhaps, can XENA implement an Ethernet port?, how about an SD card interface, USB port, it could drive a pair of ultrasonic transducers to give us similar functionality to that MS device whose name escapes me at the moment. EDIT: Kinnect.
XENA could give us a multifunction card that could evolve as people developed the software to implement new interfaces and ideas.
Software support would evolve faster if more people were trying to use XENA.
