This is true, but I do think it's something that we should have some story on supporting for some of this hardware that has a bunch of channels in one IP block that can't really interact with each other. It's going to make it a lot easier for people to think about the hardware and how to describe it. --LNKrWK8T5LDJo+fl Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJWH5e6AAoJECTWi3JdVIfQ2g4H/Ar5dygi0Ept7WJZxTow6M4O kPKsXIrb9X+n4mAd8Q5Od/mIR5A7OBw9ethut+gV5joU/1ajcrvmucbWMgKl1B5R VcKWDKdvXAIETf6m3w+qMRV0HwlVM+w+o60cfAzLEGS5NVswLRopcCdlzorac4c/ TYHuEZabOSMv93ifg/WncFtIWJ93AcoWPkwcUFjdYheVipU4TPgQ4Pt/3wCwpjcz o8+sB3r6wbwle1xM9Yepa3qGpj8rjLt4f5oYpZwPWMZqUtYq3z0gvBfXl5bGPQnP 06RGfBgf/XGSsuG0chnRFJ1C4i2cJkwRZyJO4HsXUj0qeVl4DvY3PWjMVdBLf/s= =93Ch -----END PGP SIGNATURE----- --LNKrWK8T5LDJo+fl--
