A couple of interesting things I was asked in the lab were the plugin model and the Domino server.
The first was around embedding the Domino server in the local web container and having Domino applications surfaced as off line web apps in Notes 8. This is an interesting idea – we already do JSP's, Web Services and Portlets, why not Domino apps?
Another question I was asked was about the plugin model and the real Domino server. It appears this whole “plug-in” concept – specifically the Eclipse/OSGI one – is gaining traction in the server community. Websphere already supports it and when Portal moves to the latest Websphere it will then support it.
