Any thoughts on making this list something more dynamic, web 2.0ish?   I 
think the list could be even  more useful if one could do some sort of 
faceted search on the information. 

Looking at the not-viable list it seems that many of the entries were 
considered not viable due to lack of support.  It might be more useful 
if some sort of "level of support" ranking could be used rather than 
just deem some of the tools as not viable.  If a particular open source 
app is really useful, but lacks support, it *could* be viable if someone 
discovers it, and finds it useful enough that they're willing to start 
support it.
