So, you'll have 96*200 possible PPP clients. How many concurrent PPP
sessions do you care to support?
And more importantly, how much aggregate bandwidth?

Don't understand what you mean round-robin and loadbalancing?

FreeBSD has a RADIUS library in base. The two notable users of libradius
are ppp and net/mpd. The only choice in a ISP environment I think is the
net/mpd5 port. Read the outline here:
It is very good and is actually used in large setups.

Can't reply, but keep in mind that filling a 10GE pipe is
a hard task on its own.
I *think* having more low fidelity BRASs, will serve your
needs better that a few high fidelity ones.

MicroBSD seems OpenBSD based. Can't comment on this.
You can try NanoBSD and TinyBSD which are FreeBSD based and I
believe can fit the bill. These two run with their filesystems
read-only mounted which is ideal for flash memories.
