I don't think so. There are no specific limits on the size of ICMP
ECHO REQUEST or ICMP ECHO REPLY packets, therefore the only limit should
be the IP packet limit (64KB). It does work with other IP stacks and
with the loopback interface on FreeBSD.
Poking around a bit more, the culprit looks like
net.inet.ip.maxfragsperpacket - which is set to 16 by default.
Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
