Configurable timeout is in the upstream kernel already. It's also part
of SLES10 SP1.

I think multiple IPs would be more difficult. The infrastructure is
really only set up for one IP at a time. It wouldn't be just for
heartbeat. Handling keepalive messages from multiple ip addresses would
be fairly trivial but entirely useless. We'll know the other node is up,
but won't actually be able to handle DLM requests. I suppose it's
possible to handle this with sort of a master-fallback scheme, but there
are quite a list of features that are higher priority right now.
