Diald itself has no limits. Using SLIP will limit you to the maximum
number of SLIP devices or the maximum number of pseudo terminals,
whichever is smaller. The old tap device is limited to, I think, 16
interfaces (it's a subset of netlink space). The newer tun/tap device
isn't limited at all (I don't think. I'd have to check the code...)
but if you want to use that you probably have to use the CVS diald
version. If you don't want to use the CVS code (which is actually
perfectly good and better than the last released code) you may be
able to get silly numbers of dialds by using dummy interfaces and
diald's proxy_dev capability, but I don't think I've tried that.
