Hi Steve, No, I don't think there is an accepted or stable definition of ESB... but then again, there wasn't one for OO, or SOA for that matter. I recall application servers had a hard time getting pinned down too. ;-)
But frankly, the market is somewhat of a fiasco. Some ESB's really are nothing more than what Spiritsoft did 8+ years ago. I think some (not just BEA's ;-) have some real productive value, but it's likely going to be another 12 months before the market figures out whether it wants to jettison the whole category or whether it wants to keep it and highlight certain features as more "crucial" than others. Myself, I still think of an ESB as inverting the old approach to integration. It's not about relying on one vendor's messaging platform, it's about how to adapt between contracts, independent of whatever wire protocol and transfer protocol is defining them.
