I regularly have ideas that are impossible, or forget within hours, have no clue how to implement, or no time, or all of the above. I really should make a list.

• A squeak wrapper around the Gecko HTML rendering engine.
• A simple, high quality probabilistic gossip based P2P framework (I actually started a Java version but got bored).
• A tuple space implementation on top of the aforementioned simple P2P framework.
• A mobile-code mechanism for the tuple-space, so arbitrary tasks can be submitted. The Jini model uses jars downloaded from a webserver, which isn’t really ‘grid’ enough somehow.
