There is a client vs server help file which, if I recall correctly, 
explains why you can't use server-side UGens on the client. Anything 
with .ar, .kr or .ir is calculated in the server and is not directly 
available on the client.

The buffer object has a method to get its vital statistics from the 
server: if b is a Buffer,

b.updateInfo;

It takes a fraction of a second for the information to come back. Then 
you can do b.numFrames / b.sampleRate to get the duration in seconds.

If you read a file into the buffer using Buffer.read, the info should 
already be updated.
