Just a short update about what I'm interested in (on the software side). On the one hand it's the ESB concept: Despite the former EAI solution, the very fascinating thing is that the ESB can understood as virtual – it's not necessary to have a server running in the middle.
Have a look at http://www.celtix.org.
Then I read a little bit about the semantic web and I wonder why the bigger Wiki systems still don't support it. I mean think of Wikipedia – there people do all the meta-tagging anyway. Why not using the advantages of the semantic web and create clickable topic maps e.g.?
Also MusicXML is interesting to me. AFAIU this standard is basically a translation of the MIDI format to XML. If so, I think it's as useful as MIDI is. But not further and it does not reflect the needs of modern composers or of non-western musicians. From my opionion, a Lillypond equivalent XML standard is necessary.
Finally I'm fully fascinated by Ruby on Rails (hey, the Pragmatic Programmer's book has been released since some weeks, it's as great as every book published within this series). As I like to work more on End User Development stuff (in my free time), one approach could be to write a rails cartridge fro andromda. If that was finished, it'd be great to develop a rule engine based wizard that queries the customer different questions which result in the UML structure that'd be then processed with the rails cartrigde.
Wish one could buy time and I were rich then…
