jini technology advantages and disadvantages

Advantages

Jini is open-source, meaning that the program code is freely available on the Internet and there are no fees for using it.
New services are easy to program in Java, and can be easily added to the network.
Services are recognised automatically and are made available to everyone.
Jini supports an extremely flexible network as Services and Clients can move code to where it is needed.
Disadvantages

The Client may incur larger overheads compared to other technologies such as UPnP, since it must have a Java Virtual Machine installed as well as the code that is downloaded from the network. This would not be a problem for a desktop computer, but could be challenging for small devices.
