With the prevalence of Metro Ethernet, I'd think it's probably a pretty
common thing. People run firewalls as routers (stuff like CheckPoint),
which is basically Linux or FreeBSD, although not with EGP/IGP.

MD5 authed BGP sessions might be an issue - At least with Linux it
requires a kernel patch (works for me). I'd peered with plenty of big
carriers with Linux stuff and they don't care. I probably have more
issues with a carrier I peer with who uses Juniper and feeds me my
prefixes at a rate of about 50/sec, rather than 2000/sec that I get from
others using Cisco (My gear is Cisco in this instance)
