I thought that reply was actually quite funny. C'mon, we're all grown
ups here, we should be able to deal with a witty remark like that now
and then :)

an ESB is a concept for unified messaging systems.  OSGi is a system for building and managing
applications built out of pluggable (Java) packages.  I might well use OSGi in the development
of an ESB.  Or not.  An ESB can be made in many ways, and OSGi can be used as the foundation
of many applications.

not be the same sorts of categories being seen by Ersin.  There are many ways to categorize
things, and those will determine how we see them as similar or dissimilar.  In his reply to
me, he started to identify more specifically what he was getting at, e.g., both have some
ostensibly related concepts such as service registeration.  Once we identify such concepts,
we can consider how each might approach those conceptual areas in similar and different manners.
 That will be easier for OSGi, since it actually has a specification, whereas an ESB is really
a concept, without nearly as fixed a form.
