Hi Oliver,

yes, this is a good idea. Please contact Daniel for creating a project page 
on Wiki.
I will take the info for the ECT-Homepage, that will appears in the next 
days.

Most (really all) projects are cocerned to FE-issues, i'm glad that now 
there is an BE Issue. But it could be
useful for FE as well, cause prototype techniques are also good for 
presenting data on FE Page like drag&drop etc.
