Things are winding down on Tapestry for the moment. The code is stabilizing and I'm working just on bug fixes, documentation and some improvements to the JBE.
I'm also planning my next framework: Sabertooth. It's yet another approach to accessing database data. It borrows some ideas from NeXT/Apple EOF and J2EE Entity EJBs but is architected to work well in a web application environment.
I once read a quite from someone on the Quake team who said "all computer science is caching" at that's very true.
