he SANA-II v3 device specification does not require devices to cache or buffer information in any way. That makes it difficult (if not impossible) to share the device with another stack looking for the same data. The device could be written to service multiple requests for the same data, but since we can't make any assumption about the device apart from what's documented in the specification, I'd say support for uIP or lwIP alongside AmiTCP or another stack is out.
Actually later SANA2 speifications updated this, making it mandatory to handle multiple readers properly (that is, the packet is sent to all readers, rather than sending it to the first reader in queue).
