• Client establishes a bidirectional connection through Glacier2 router for callbacks
• Server provides wake-up service that calls back to the client's alarm clock implementation

The reference to 'Ice Greeter' demo is incorrect. Based on the context, this should reference the 'Ice Callback' demo since this Glacier2 demo is similar to the Ice Callback demo mentioned at the beginning.

Suggested change

	> server provided in the [Ice Greeter][1] demo and does not depend on Glacier2.
	> server provided in the [Ice Callback][1] demo and does not depend on Glacier2.

The link references are inconsistent with their usage in the document. Reference [1] is used for both 'Ice Callback' and 'Ice Greeter', but they point to different demos. The reference on line 46 should use [2] for 'Ice Greeter' or the text should be corrected to reference 'Ice Callback'.
