Well, IMHO this isn't the best idea, really :-) Even for a webapps the  
speed will be magnitudes better if they sync changes to a  
'local' (middleware) cache and work on top of that.
Running a SQL query against an RDBMS is (very) much faster than doing  
a REPORT via HTTP.

Best of all, it works with GroupDAV servers too! (eg plain mod_dav) ;-)

Greets,

PS: I still think it would be pretty nice if a webapp could directly  
use the SQLite structures of CalServer. Somewhat similiar to SOGo.
