Sounds really good.

Keep in mind, that you need one more feature IMHO to use the cache  
and for many more situation, that also can be improved through  
"Vserver can send events to Vclient" - messaging / notifications.

When implementing cache systems on not real-only-systems there is  
always the difficult to decide between using as much cache or as much  
actual data as possible. Solution might be, that a client can  
"subscribe" to some data (record, table row, ...) and get a  
notification when this data is changed / deleted on the server.

Now the client have two options depending on the type of application:  
Reload the data in background, so that always all data in cache is  
actual OR do an invalidation of the data and knows that the data must  
be refreshed the next time these data is requested.

Of course all this can be done separately, but why build an  
additional own communication over the network, when the database  
connection is already there ;-)

Would be nice, but if you asked me I prefer the stuff above much,  
much more ;-)
