No issues that I know of. We use IPMP on our DNS servers and haven't had 
a problem. It should be transparent to BIND anyway.

Not sure what you mean there. We have outbound load-balancing (multiple 
non-DEPRECATED) interfaces on our boxes, so that they can, in theory, 
take advantage of the full bandwidth of multiple upstream connections 
for inbound zone transfers. Is that what you mean by "active" mode, or 
what? The IPMP docs, as I recall, don't use the terms "active" or "passive".
