Can Apache Thrift push notifications to clients?

[Powers, Sean]

I'm looking to use Apache Thrift to have one client send data to the server and 
then have the server push that data to any clients. Is this possible, or would 
the client need to periodically check for new data? I'm looking for something 
similar to WCF's callbacks.
I'm pretty new to Apache Thrift and I'm using it in C#/.NET currently and will 
likely have a Java client. Thanks.
