I'v given up fedora, looks like lubuntu is so fat the best for me.
And my map widget is in Beta . http://smapshow.appspot.com , I will start building some showcase when I get time.
Now it supports WMS and part of WFS. In terms of WFS. The short term goal is the function to edit layers from geo server. Feel a little bit sad though, since no one or company supports me to do the thing I am good at and interested in, and I will never have chance to lead a team to achieve something really remarkable. People just want to do the easy things and get paid, and who can we blame.
I will invest some time on GWT styling(theme). The GWT should have been more popular, if it had some nice themes. I really admire the flexibility of GWT, it's quite extraordinary comparing other RIA framework. People may miss the point that in fact With GWT, we can create any types of web page, not necessarily to be desktop-like.
