I prize all FLOSS effort, but try to observe a thing: here is a "PRM" (CRM), there a webmail, there something else, ALL not integrated AT ALL. It's not possible to integrate them since they are different applications. Now try looking at classic model: anything is a single application, from the OS to user-programmed simple automation. That's true for Smalltalk workstations to LispM. This is so effective that I found today far simpler and power using Emacs than any other modern software, even if modern Emacs just run on top of something else, lacking a LispM underneath, and even if it's development lag in many areas for modern usages. So to say: all FLOSS authors, instead of trying competing with commercial tools their way, do your best to resurrect the old way. Please choose to learn classic languages like Lisp (CL or anything else) or Smalltalk (see Pharo as an example) to rediscover the idea that there is NO APPLICATION but just one with various bits of code plugged is as needed. So for instance a PRM can include a mail system, a complete agenda/calendar system, ... without trying the Greenspun's tenth rule way, and fail as usual.
