By far the best explanation on the lazy web of what OSGi is. :)
On my end am becoming increasingly curious about OSGi. Wonder how long till I succumb and scratch that itch and plunk down and do some happy code.
There are a variety of usage scenarios I can think right out of the bat. Wether its a fat client or a beer-belly server, who would not love upgrading your JAR dependent lifestyle with SOA concept based OSGi goodness?
